These likely were parts of three-card salesman samples. The correct versions are on the top left of the two sample cards and the error right under it. The two right versions of each are the correct # and info versions from the correct cards. The ones at the bottom are the cartoon that is also used on the errors. Notice that the error cartoons do not have all of the red ink. The cartoon on the correct Whitey Ford has the answer on two lines only, while the error card above it uses three lines with a hyphen. I did a lot of research using COMC to find the Billy Martin cartoon that was used in the DeMaestri error card. I believe the sample cards had two of these on either side of a third player who had the commercial on the back, as is seen on the Frank Robinson card back.

Notice on the closeup of the cartoons, that there is some difference in the colors as well as sentence structure on one.
