The tradition began in the U.K. around 1946 at what was then the International Circus Clowns Club but is now called Clowns International. A member named Stan Bult started recording clown images on chicken eggs with the insides blown out. It started as a hobby, and, like many hobbies, it just grew. Mr. Bult kept his collection at home, occasionally loaning it out for show, such as at the 1951 Centenary Exhibition of the Crystal Palace.The collection continued to be lent out after Mr. Bult's death but sadly most of the eggs were thought to be destroyed in an accident at one such exhibit.Clown Bluey became chairman of Clowns International in 1984 and resurrected Mr. Bult's practice of recording clown members' faces on eggs. This time a professional artist was used and the faces were painted on china-pot eggs instead of chicken eggs. Over the years, many of the lost older eggs have been reproduced, and new eggs are added frequently.According to Clowns International, "The eggs are not just a record of the clown's facial makeup, but an actual portraiture in miniature." In addition to paint, the artist uses samples of the clown's costume material and wig-hair to produce an eggs-act match.
