Topps printed the various series of this set on duplicate 100-card sheets. The 1st series consists of 80 subjects; therefore, Topps's printers
had to Double-Print two rows of cards to fill out their 100-card sheet.
This 1st series sheet is a partial sheet of 50 cards, which comprises of cards #41-80. Note that cards #51-60 (top row and 3rd row down)
are Double-Printed.
The missing top half of this 1st series sheet comprises of cards #1-40. I believe that the row consisting of cards #31-40 are Double Printed.
Dave Hornish (toppcat) is our resident expert on Topps sets......and, perhaps he will chime in here with additional insight regarding this great
post-war set.
