Hi. This forum was recommended to me as the best place to seek info on the nature of the 1959 set's white and gray backs.

I've found what seems to be consistent information on cards 199-239 and 241-286 being found in both white and gray.

But there seems to be much conflicting info on the cards before and after. One widely circulated collecting publication's article referred to all other cards having uniformly gray backs. But that seems clearly wrong -- my observation says at least the first series has (only?) white backs.

I'd appreciate being referred to any definitive source of information. Thanks
