Well, not exactly a misprint, but more like one of those moments: "If it can go wrong ..."
The unusual episode happened with Eryk Lipinski's poster for Dostoyevsky's play, The Idiot, in the time leading up to its staging in 1968. Warsaw's Dramatic Theater, built in 1949, is a large venue capable of staging 2 or more performances running simultaneously, including within a more informal space known as Sala prob (Rehearsal Room). The Idiot was originally scheduled to be staged in Sala prob, and the poster indicated it as such when it was printed in an edition of 2,000 copies. Fortunately for organizers, the posters had not yet been shipped out when ticket demand for the play forced a last-minute change of venue to the Main Stage at the Theater, but producers had to scramble to re-identify the location in time for Opening Night. The print house ended up entirely reprinting a small quantity and covering remainders with a small strip of yellow paper over the erroneous location.
