Perf 14 x 14.75
4 post office sheets, each, single pane, 12 rows of 10.
After a brief appearance of the young
farmers type B, the medium format reverted to type A for
the remainder of the decimal period.
A most interesting feature of this layout is the
Antarc 8d, which in appearance
would seem to be yet-another layout. In fact, it is a mere (but cleverly
done) type A printsheet with the central perforating pins removed to create
such a large design.
