The below 3 cards are from 1993 sets of Upper Deck and Score. Damion Easley and Chuck Finley appear to be wearing 1960's California Angels throwback jerseys. There is a record from August 16, 1992 of the Angels wearing Road Grey against the Oakland Athletics, who were wearing 1968 Home Athletics Vests.
Chuck Finley did pitch in the August 16th game, as well as home games on:
Another look at the two Easley cards show a green fence, and as you can see below in 1992 Angel Stadium had blue fences. Possibly the Easley cards are from the Oakland game and the Road Grey jerseys show just extremely light. The example in Bill Henderson's tome certainly don't appear to be that light. The Bryan Harvey card doesn't appear to look that light either, but Occam's razor would seem to say that is the case.
That still leaves the mystery of what game the Finley is from. It is obviously a white jersey. The fence is blue. It doesn't match the jersey from 1992 or 1993.
