I'm pretty sure they were printed in one series. Topps printed 1960's and 70's cards 264 cards per sheet, here is one half of that sheet, the more commmonly seen 132 card sheet. I'm fairly certain the other half would be identical to these half sheet.
Rows 1 thru 4 are reprinted in rows 9 thru 12. Row 5 is also reprinted in row 8 but upside down, therefore rows 6 and 7 have to be the sp's, includes Billy Williams, Drysdale, Yaz and Willie McCovey off the top of my head.
55 cards printed twice = 110, 22 cards printed once = 22, total = 132
That's it for today's lesson, John
