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:

• May 8th against the Blue Jays
• May 13th against the Tigers
• May 29th against the Indians
• June 3rd against the Orioles
• June 13th against the Royals
• June 19th against the Athletics
• June 29th against the Twins
• July 17th against the Yankees
• July 22nd against the Blue Jays
• July 27th against the Mariners
• August 11th against the Brewers
• August 28th against the Red Sox
• September 2nd against the Indians
• September 8th against the Athletics
• September 20th against the Twins
• October 1st against the Royals

Damion Easley was not with the team until after August 13th.  He played in every other game at 3B, except the 10/1 game in which he played SS.  

​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.  

2020 Topps cards have hit the shelves, and the plethora of Reds throwback jerseys from last year are well represented.  

Other throwbacks were this 1969 Cubs Walk-off Team card, Phillies all blue alternates as well as their Cream colored alternates, Brewers alternates, White Sox alternates, and an Astros 1989-93 Rainbow sleeve.  It is getting to the point I may rethink counting these alternates in my database and card collection.  Way too many teams seem to have an alternate throwback in their uni rotation now.
