To avoid last minute conflicts and unnecessary work for the participating artists, the curators asked the artists to turn in mock-ups that could be approved ahead of time by the CTA.
The show "Critical Images" was scheduled for a month long run in May, 1985, and in late March, Artemisia submitted the mock-ups. After a few weeks, the CTA informed the gallery that only eight pieces would run in the show. The eight works rode the trains, and all works were displayed in the gallery along with flyers distributed with statements about all eighteen artist works. Artemisia then received a four-page letter from the CTA outlining the reasons for rejection.
