The trick, which was popular with the magician Imro Fox, involved two birds: one black and one white. During the trick the birds emerge from the pans with the wrong coloured head. By the end of the trick the birds are reunited with their correct heads. The last public performance for these dove pans was when they were loaned to Mike Caveney so that he could recreate the trick as part of the LA Conference on Magic History in 1999. The pans are nickel plated brass, made by an unknown manufacturer.
