Here are some scans of Texas Rangers Pocket schedules though the years. The majority of these are clickable for larger images. Some of them are not, however. If you have a pocket schedule that I do not have here, or have one in a better/larger quality than I have, please email me. I’m interested in piecing together the complete history.
The last one I’m not sure about. I think it’s the flip side of the 1972 schedule, but I don’t know that for sure.
