1975 Topps #511 - The Texas Rangers. I have always thought that the 1975 set would have looked better in the 60's what with the color variations and such. Of course, if Topps had agreed then I wouldn't be able to pick up any for my Rangers collection.
By the time I started collecting in 1987 Topps had done away with the team photo cards. Too bad in my book. I remember getting these from the years they were issued and thinking they were the coolest thing. Even hung on to the teams that I didn't like, just because I thought the team cards were neat. I thought it was great a few years ago when Topps brought them back.
