I have to wonder how a hobbyist in 1951 would even have become aware that the 11-card set of MLAS contained three non-issued rarities. Probably not by going into a mom&pop store and buying 100 wax packs and finding dozens of the eight commons and none of the other three. It was only later that highly knowledgable hobby vets received inside information about the Roberts, Konstanty and Stanky cards, and were able to request them from Topps. At least, that has been my understanding.

I think it was highlighted in Card Collectors Bulletin as Woody Gelman was very active in the hobby then and had just started working at Topps in 1951-52, although his art agency had worked on the account for a couple of years prior. Woody is the man who rescued the three MLAS short prints.
