1965 Topps Uncut Sheet1 Fifth:Sixth.jpg

Is this known already?

In looking at the 1965 Topps uncut sheet from the auction (above), I noticed that there were only three Roger Craig cards, whereas others seemed to appear four times across the sheet(s). So I started to examine the entire sheet and found out that a whole bunch of cards only occur three times.

Among them are:
1965 Topps #411 Roger Craig
1965 Topps #396 Frank Bertaina
1965 Topps #428 Bob Shaw
1965 Topps #383 Felipe Alou
1965 Topps #420 Larry Jackson
1965 Topps #404 Stan Williams
1965 Topps #405 John Roseboro
1965 Topps #419 Ruben Amaro
1965 Topps #382 J C Martin
1965 Topps #372 Clay Dalyrmple
1965 Topps #410 Luis Aparicio
1965 Topps #406 Ralph Terry
1965 Topps #386 Cubs Rookies
1965 Topps #398 Reds Rookies
1965 Topps #422 Aubrey Gatewood
1965 Topps #399 Ray Herbert
1965 Topps #436 Don Elston
1965 Topps #378 Chuck Estrada

...and then I stopped checking.

Are the cards listed (as well as the others I didn't get to) considered SP's?? If this full, two-sided sheet is official (and the only one used), then the quantity of some cards printed was only 75% of the number printed of other cards (it's late, so I'm sure that was poor grammar, but I digress)...unless there was also a second version of the sheet that included more of some cards and less of others to balance out the totals??
