Found this limited, but recurring print variant on the 69 455 Siebert card. Above the first "I" in Indians there is what appears to be a pen mark, but it is indeed a recurring mark. This is another variant that looks much more obvious in hand.

67 Siebert
 

Larry---had not seen that one. I do have the one with a blue line to right of the bill of his cap, one with a broken spot in that same "I", and one with a reddish brown color between his legs. Isakur has the first two of those up on ebay now

Different year, that one is the 1967 :D. Same photo, though.

My Bad:(

Even worse, in checking my set I have that one. I need a "normal" one

I thought I was losing my mind looking at other 69s looking for these other variations, being a 67 explains why I was not finding them?!?!

I would like to say I was just being devious rather than stupid....but

I noticed on two of my versions of this card that there is a little red line to the left side from his right ear down to the left margin. Obviously it is recurring and common to find.

Also have one with red dot to to left and below ear

Red at bottom ?

That's probably just a misaligned sheet going to the magenta plate.
