The other series 4 slit, as indicated by Kevvy's earlier post.

Of all the series in all the sets I've posted on at my site, the 1969 series 4 is the only one with short-prints, defined as such by my admittedly minority-view definition - a short print is any card printed in lesser quantities than the majority of cards in its series.

Pretty sure that only a 99 card series would result in such short prints.

On full sheets:

66 cards - each printed 4 times (full sheet)
77 cards - 44 printed 3 times, 33 printed 4 times (over)
88 cards - each printed 3 times
99 cards - 66 printed 3 times, 33 printed twice (short)
110 cards - 66 printed 2 times, 44 printed 3 times (over)

The 1967 7th series has that 'error' with the Pinson row, I think, printed 5 times, the Red Sox rookies row printed 4 times, and all others printed 3 times.
