In case you ever wondered about some of the differences between Topps and O-Pee-Chee back when OPC was simply Topps' Canadian brand, I just happen to have both versions of Tom Underwood's 1984 card. As you can see above, Tom is pictured with the Athletics but labeled as an Oriole on his O-Pee-Chee card. There is also the helpful "Now with Orioles" notation floating on top of his groin. It makes him seem like a snack food that's been repackaged by Madison Avenue. "It's Tom Underwood by Nabisco! Now with Orioles! Mmm, taste that orange and black!"
Taking a gander at the 1984 Topps version of Underwood's card, you'll see essentially the same card, but with the Topps logo, the Athletics coloring and wordmark, and a squeaky-clean text-free groin. Tom was something of a latecomer, signing with the O's in February of 1984. His Topps cards were printed and shipped by then, but it wasn't too late to assign him to the Birds for the North of the Border cards. So I guess there was some tradeoff for those Canadian kids who waited patiently for their brand-new cards.
