This one depends entirely on how crazy you are into print errors, but while looking at high number 1972 Joe Morgans on-line lately, this thing jumped out at me. Since I've seen a bunch of different ones now, it is definitely a recurring defect.
Take a look at the 'T' in "TRADED." On the lower right side there is a large round anomaly. With the color seemingly matching the dirt appearing behind it, it's possible this is a 'missing piece of a letter' variation. Sort of a poor man's (which is a joke, because this 'Traded' card is always expensive) 1967 Ed Spiezio. Either that or it is a fisheye...
