W513 Strip Cards

[Cozumeleno]

I am working on sets of the W512 and W513 strip cards. While I have noticed no variances in card stock on W512s, I have come across (several times now) a second type of W513.

Standard W513s have pictures that are pastel/lighter in nature. However, there is a second type that has significantly more vibrant color and is printed on a thicker stock. Comparing the two, I'd say that the one is about twice as thick.

The first time I came across them, I initially dismissed them as fakes. But there aren't really players in W513 where forgeries would make much sense. The biggest stars, Ruth and Cobb, are in the earlier W512 set. I then came across another one a few months ago and just now came across a third one that I won in an auction. Further, under a loupe, the print style is the same on both.

The other difference is that when you flip them over, the color of the cardboard is different. The 'regular' W513s seem to have a lighter stock while the thicker ones looks like more 'traditional' brown cardboard if that makes sense. I'm wondering if the thicker ones could have been part of a poster or something. I have not seen any references to these anywhere or even references to fakes or reprints.

Does anyone with W513s know about these two types or the possible origin of one? If you have any W513s in your collection, I'd love to know if you have any of the thicker types and would like to hear your thoughts.
