The Junior Baseball Federation is an organization in Philadelphia. Here's a quote from their website -
"The JBF was formed in 1948 by Bob Carpenter, owner of the Phillies, and Connie Mack, manager and part-owner of the Philadelphia Athletics, to coordinate and provide funding to the city’s youth baseball programs. The earliest JBF benefit games were exhibition games at Shibe Park between the Philadelphia Phillies and their hometown rivals, the Philadelphia Athletics. The scheduling of these benefit games was later changed to regular-season games and this year, the Phillies have identified five games for which a JBF voucher can be redeemed. "
The Phillies would invite teams to participate in a yearly benefit game. Participating teams would not get paid, but the visiting team's city youth baseball programs would get a portion of the receipts.
I have four programs from the years the Orioles participated, 1964-1966 and 1972. While the covers are similar, they did a nice job with articles relating to the Orioles inside. The 1972 program has an article about the Orioles trip to Japan in 1971. I believe the Orioles also played in the 1968 game, but I don't have that program. If anyone can verify all the years the Orioles played, that would be great.
I've seen programs as late as 1977. I'm not sure when the game was switched from an exhibition to regular season voucher games.
