Paper Sumo Wrestling - 1930s Version

Menko have always been viewed as toys rather than collectibles by most Japanese.  They were meant to be played with, destroyed, and thrown away with very little concern for value, longevity, and collectability.  As such, a good amount of the 1930s menko that I run across have been well used and loved.  That is okay with me as the stories the menko could tell/do tell are what helps drive me in the menko hobby.  One very popular game that kids would play with menko is called kami-zumo, or paper sumo.  In a nutshell, paper sumo wrestlers are placed on a board and then that board is tapped which vibrates the wrestlers moving them around the ring.  The paper wrestlers eventually tangle themselves and knock each other over.  Last one standing wins.  Check out this 15-second video to give you a quick idea:

In the 1930s, this game seemed to be all the rage as I have dozens and dozens of R-series menko that were cut along the bottom and along their arms to allow them to stand and engage in paper sumo.  Here are three such examples from the R392-2: 1939 Rikishi 4-5-6 set.

You can see all the cut marks (two rikishi lost their left arm in battle, yikes).  Here is what they look like stood up:

Good luck to all the wrestlers that are competing this tournament.  It'll be an exciting 15 days for sure.  Sayonara!!

Silver Bromide Poisoning - The challenge of 1930s and 1940s BB-Series Black and White Bromide Cards

I'm a completionist when it comes to collecting sumo cards.  I want to get my hands on each and every sumo card made.  I really feel it is the challenge of being able to document and catalog a new set for the first time.  Nothing is more satisfying than reuniting individual cards back into sets which is probably how a good amount of set collectors feel.  This is how I collected back in the 80s and this is how I collect now.  With sumo cards, however, it does present some challenges.  First, my disposable income forces me to pick and choose as I can't have everything, so I have had to prioritize.  Second, the different kinds of sumo menko and cards is vast (believe it or not) and so this economic limitation forced me to get the more common stuff early on in my collecting year.  Now I am left with the "harder" and more expensive stuff.  Alas, if I had them all there would be no need to collect anymore, right?  So I am not complaining.  Lastly, out of all the types of sumo cards out there, the 1930s and 1940s BB-Series Bromide cards are a hot mess.  I say that with fondness for the challenge, but I knew once I seriously dipped my toes in the 1930s and 1940s BB-Series Bromide sumo cards, my sanity would be tested.  Well, now that I am in my second decade of collecting sumo cards, I have come to the realization that the BB-Series sumo cards need some catalog and checklist lovin' and given the respect they really do deserve.  Why the hesitation you ask?  Let me quickly sum up the challenges 1930s and 1940s BB-Series Bromide Cards.

- There are over a hundred different sets (probably, I'm just estimating here) = Lots of auction action = $$$ & ¥¥¥
- Only a small fraction (less than 5) have any company marks = Need to figure out which cards go to which sets

- Blank Backs (see above) = Need to figure out which cards go to which sets based on front design
- Out of a hundred different sets, how many ways can the front design change? = Answer, not a lot in most instances = In-depth study needed to sort them all = time, time, time
- Most were printed prior to WW2 = scarce = beat up = patience for them to come to auction

The 1930s and 1940s BB-series bromides were usually (not always, though) actual photographs.  A few used the halftone printing process.  The term "Bromide" or in Japanese "Buromaido or Puromaido" ”ブロマイド　or プロマイド”　comes from the term 'silver bromide.'  Silver bromide is a yellowish chemical and when mixed with a gelatin was a photographic emulsifier.  Once exposed to light, the silver bromide darkened into metallic silver.  The areas that weren't exposed to light do not change and stay silver bromide.  That is why these bromide cards have a yellowish tint to them in the light areas and silver metallic on the dark areas.  In fact if you hold these card to the light just right, you can see the shiny silver metal reflect the light.

Here are three cards from the BB391: 1939 Black Shikona Bromide Set (Notice the hand-colored tint on two of them).  These came from three different sources over the years.

The unique things about Bromides, which is different from Menko, is that Bromides were meant to be collected and viewed, not used to play the game menko.  So a lot of times they were glued into scrapebooks or pasted into albums and consequently have a lot of back damage.  Here is one such book called a Puromaido Book プロマイドブック.  You can see the slits in the book to insert the Bromides.

It will not be a quick process, but the 4th edition of my book will have a greatly expanded BB-Series section as I will have added many more sets, corrected numerous cataloguing errors, and refined the research in the area.
