Del Ennis and Dick Sisler. As far as I know, it's the only baseball card the two share exclusively.
This card was part of a set of postcard-sized cards issued at every Friday home game throughout the 1983 season as part of "Nostalgia Nights" sponsored by Girard. Fans attending Friday home games received a postcard from the Greatest Moments set and a postcard from the Greatest Players set. In total, there are 26 postcards in both sets along with two header cards.
I must have attended a few Friday games that season, or at least my Dad or my Pop-Pop did, as I had several of these postcards (in their original Gerard envelopes) already in my collection. I've been adding cards I need from the set one at a time over the past decade, and I have very rarely seen complete sets available for sale.
The Ennis/Sisler card is part of the Great Moments set, celebrating the team's National League pennant in 1950. It's a cool card on its own, but the thing that clinched it for me that I absolutely had to have this very card was what was on the card's back. Both Ennis and Sisler have clearly signed the back of the card in easy to read black pen. Both men have since left us, with Ennis passing away in 1996 and Sisler following two years later in 1998. I'd love to know how the original owner of this card tracked down both signatures. Were both Ennis and Sisler at the same signing event somewhere? Or did the original owner procure one signature at some point in the mid-80s and then have to wait several years before getting the second signature?
One thing is for certain: This is now one of the most treasured cards in my Phillies collection and I know for certain that my Dad would have loved this card too.
