I think Dale may have posted it either in this thread or the 52 Gallery thread. I picked one up after seing that post. Scarce but recurring

eBay happens to be unusually rich with them right now at the moment, but I've seen off-center cards of Boyer missing the magenta, so I assume that the mark was only on one of its placements on a full sheet and is thus only possible on Boyer's that came from that particular sheet slot. But what do I know!

At least more than me :)

Definitely not when it comes to post war variants, sir!

Recurring print error: incomplete circle on back around card number.

1965 series 7 yellow line
 

I believe that line was a demarcation mark used by Topps to meld the 4x print rows with the 3x print rows. I have seen Sparma, Downing, and Mets team with the yellow line at top. These cards are in the row below the Lopez row. In addition, I have seen Gaines with the yellow line at bottom.

I collected most of the variants i have at a time I was blissfully unaware of the fact some were actually related. Guys like Cliff and you explained a lot of them

Truthfully, I didn't really notice these until I was studying my 1968 cards, where this pattern is prevalent. I then went back to other years to discern if it had occurred before. Cliff then educated me about the practice.
