Here is a 707 block
from the 1977-1982
" Floral Definitives" which has a time stamp on stamp of 1977. The perforation measurement has been written up as 12.0 x 12.5
They are another set of 1979-1983
" Floral Definitives" which has a perforation measurement of 13.0 x 13.3
My 1977 bock measures 13.0 x 13.3Am I missing some thing..???
