Hoping to help here with the dark ad for the Keystone box - the one with the word "PLAY" below it and Detroit,Michigan above. That is definitely from American Boy Dec. 1912. I have the original magazine and just double checked it. So that's certain. ---JASPER
Hoping to clarify here - The golden yellow is pretty easy to explain. All of the marbles in this first Akro box were not onyx marbles, Some were just game marbles - jade + turquoise.
In Hansel's first Akro box there are 6 "golden yellow" game marbles.
About the white onyx in the 1914 Playthings ad - I don't know anything about the Sept. 1915 date for MFC starting to make white onyx marbles. But I do know that December 1914 is only months before the Sept, 1915 production date. White onyx might easily been in development then. Akro was a
local jobber. They might have seen the development and asked for a run, or Akro might have asked for a special run just to offer something different than MFC was offering. Akro may have been the inspiration for MFC's introduction later. What I am saying here is speculative, but quite possible.
Another curious point to notice here is the the Sept. 1915 ad from Playthings Magazine features a row of white onyx right down the middle of the box! The articles and pictures for a September publication are in the works long before the publication date. I think this is evidence that the white onyx was produced before the September. It makes more believable Akro's claim. Besides, why would they offer something they couldn't supply? Another thing to remember is that MFC made onyx marbles by combining swirls of white with transparent colored glass. They also made clear marbles for furniture claw feet. It would be a piece of cake for they to add white to clear to make white onyx =- even much earlier than 1914. ----JASPER
More help, I hope. The ad on the page that is dated 1916 is in my reserves as being from 11-1915. I have the same picture that Steph shows, but I can't read the date on mine.
I'm not sure why I have it down as 11-1915, but I make a point of never putting down a definite date like that without knowing it for sure. Another point here - sometimes a 5 can be mistaken as a 6 if a piece of dark material connects the open circle with the straight line above.
I have a question. Does anyone have an ad for this box from 1914. I once bought a full year of American Boy magazines on ebay. I searched them diligently, but found none. It may be that they were too busy with moving to put out an ad. I have also heard that there was an ad for this box in 1916, but I have never seen one. It is unlikely because Akro developed their small display boxes in 1915. They were much lower priced and therefore, a lot easier to sell.-----JASPER
