In poster collecting circles, both parts of Czechoslovakia,
the Czech Republic and the Slovak Republic are still known as Czechoslovakian
posters. Each republic is about the size of the state of New York in the
U.S, but the vast majority of the posters that are seen on the collectors
market come from the Czech Republic where the majority of the films are
shown. Both republics issue film posters the same size and the majority
of them look almost identical except for a few minor differences. Here
are the dominant sizes for both republics.
11x16 - called 'petite', or 'A3', the width and the height will sometimes
vary an inch or so.
23x33 - this is the standard size, similar to Germany and called
by collectors an 'A1'.
12x36 - called 'nudles' (pronounced like 'noodles') similar
to the U.S. insert but also varying an inch or so both ways. Nudles
were more common in the 1930s - 1950s, with the pre-war size quite often
closer to 11x33 and the post war sizes varying from 12x36 to 12x38.
