Very cool on the Bowman find! I'm going to have to go looking now as well. I wonder if one was a wax version and one was a factory version?In all of the glow back discussion, did I miss any discussion of 1991 Bowman? If this is all old news, my apologies, but it was news to me...
I was completely unfamiliar with all of this glow back stuff, so I went out and bought a brand new "Use Only For 1991 Topps UV/Black Flashlight ," brought it home, pulled out a couple of 1991 Topps Kirby Puckett cards, once again confirmed that my Desert Shield is legit, found that I had both glow/no glow of the regular 1991 Topps #300 , and excitedly added a card to my "have list."
Then I started flipping through my Pucketts...
I believe there are two unique versions out of these three pictured. The only reason I put all three in the picture is that the one visible difference under regular light, is that the two glow cards, the two on the left, are darker on the front than the third, no glow card. I do not have many 1991 Bowman, so my sample size is small, I don't know whether the lighter front print is just a random defect, or a regular indicator of glow backs.
In terms of variations of glow cards, I have two "1991 Topps Puckett blank front/glow back" cards and one "1991 Bowman blank front/glow back" card. If anybody is interested in my extra Topps blank front/glow back, let me know. And if anyone has either the Topps or the Bowman Puckett with a blank front and no glow back, I'm in need of those.
The only other glow cards I found from that era in my Puckett collection were a bunch of the Star Company Puckett sets have print/stock that has the true glow effect with the text. However, the glow seems consistent through the individual sets, and I don't have any duplicate Star Company sets, so I can't really compare or contrast, and I didn't find anything immediately leading me to believe there are variations out there.
Not a card that glows, but just a random oddity I found while using my brand new "Use Only For 1991 Topps UV/Black Flashlight " is this with 1989 Donruss...
These are the usual variations that differ with "INC." and "INC" as well as "*Denotes*" and"*Denotes"
With both Puckett #182 and Puckett #BC-1 (Not pictured) the backs of all three cards look the same under normal light, but under UV/black light, the "INC/*Denotes" versions are a different color stock than the others. Again, not really any new variation, it didn't really glow, but just a UV/Black light oddity with the stock I guess.
