So, the history is that this is an early bag -- presumably after the Marble King company was incorporated in 1949 but before they started making their own marbles (which was sometime around 1955). So looks like Berry Pink just gathered together some colorful marbles for the ad, without worrying too much about whether he could match them when the orders started coming in.
Mr. Pink bought the factory from Mr. Alley ... so that explains the Alleys in the package. He jobbered marbles for Mr. Peltier ... so that explains the Peltiers in the package. I think I also see some Akros in there ... and the Akro company had gone out of business around that time so there may have been some surplus floating around, but I thought Master got that. So ????? (Ric do you see Akros?)
And what is that marble in the bottom right -- white with orange and yellow stripes?
