There is a recurring print flaw on the 1984 Topps Buddy Bell and Johnny Ray cards that are side by side on a 1984 Topps uncut sheet, I don't believe it reaches the Boggs but it may affect the Kittle. Something partially blocked the final black ink coat of the border lines in the printing process. I knew about the Bell for years but recently found out about the Ray.

Good ones Cliff. You are on a roll

Seems to be paired with the white splotch print defect over his left elbow.

..here's lookin' at you , kid. It got a "6" and no Q for PD.... not complaining....

Had not seen that one John

You can call it the Marionette version, since it looks like he's hanging from strings. ;-)

Here's another I spotted today. COMC makes it so easy by putting multiples of a card right next to each other:
Recurring Print defect of a fake apostrophe on 1964 Topps #274 checklist. #287 looks to say "Rookie Star's" but it is a spot.

3 of the first 12 on COMC's raw page have the errant spot.

Hey John---it is my impression almost all of the 1960s and many 1970s Topps CLs are DPs and variances can be found in most of them, albeit sometimes pretty subtle cropping differences.

On this one, not only the errant dot but note the 281 number and the K in Ken on 277 have defects. On the other version they are ok, although the R in Rookies in 281 has a slight defect on that version. Plus there is a very slight green bleed into the boxes in the version you posted. They are clear on the other version. The dot version seems to appear only on the version you posted

Recurring black print defect in the top border. Most fisheyes in 1973 Topps on the borders are white. There are at least 4 of these on COMC.

Picked up a Gossage rookie for my set, and noticed it has quite prominent 'yellow bleed'. Haven't seen it mentioned before, but I only casually collect 1973's.

Note the yellow patch in the grass by his knee, the yellow on his pitching arm, a spot on his glove, and on his 'personal area':

Good thing the yellow is not limited to the latter
