In the 1950's & 60's, it was fairly common for teams to travel to locations outside the normal radius of their spring training home, especially near the end of spring training. Teams would often recognize and thank their minor league affiliates, by playing an exhibition game there, just before the regular season was set to start. Even today, the Orioles will sometimes travel from Sarasota to Norfolk, to play a game against the Tides, if they are scheduled to open the season at Camden Yards.
Programs from these games are cool for a couple reasons, you can pinpoint the date of the game and quantities of the programs are fairly limited.
Here are a few programs from the 1957 and 1958 seasons.
