1960 Topps variations

[Meliah]

In the 1960 Topps baseball card set #'s 375-440 have two versions, one listed as normal and the other only listed with a "wb" at the end. What the heck is the WB? White border, white background, white back...? Any help would be mucg appreciated

Okay, figured out that it means white back. Does anyone have a regular 1960 and a white back one they could scan so I could see the difference please?

Though not the same card number the lighter back is a white back and the darker card is a grey back.

Thanks, that clears it up for me Not much of a difference there unless you have them next to each other.
