SCB on his stamp blog reported that his 1908 Franz Josef issue stamps for the higher denominations (60 Heller particularly) were found both fat and wide, and tall and thin.....
http://www.stampcollectingblog.com/...p-series.phpHe asked for other examples, and here is mine.

Clearly the 72h and 1k also are found in different sizes.
The perforations were:
1st Scott 123: 12 1/2 X 12 1/2
2nd Scott 123: 13 X 12 1/4
1st Scott 124: 12 X 12 1/2
2nd Scott 124: 12 1/2 X 12 1/4
Apparently the wet printing can lead to different sizes.
Scott makes no mention of different size stamps for this series, and apparently neither does the regular Michel catalogue. (The 1916-18 "Coat of Arms" issue is reported by Scott to be in two sizes.)
Apparently more specialized Austrian literature does make mention of the different sizes, but I wonder how many collectors know how common this size differential is for this issue?
