Anthony "Tony" Diano was a businessman in Canton, Ohio and owned a farm known as the Diamond "O" Ranch, or Diamond. There was a dairy farm on the farm. in the 1930's he began to accumulate animals some of which were a herd of buffalo, a camel, a polar bear, hyena, cheetah, hippo, small monkeys, elephants and even a giraffe. Later his company was called Buckeye Circus Corporation.

Diano constructed a ring barn, a bull barn and barns to hold wagons and trucks and came a circus quarters. He leased out animals to different carnivals and circuses and motion pictures. 

Diano and Ben Davenport combined their show properties in 1953 into Diano Bros. Circus, but it did not last out the season. In 1954-55 some of Diano's animals were on World of Mirth Shows, a railroad carnival and his stock car was used on that show. In 1958-60 these animals were on Cristiani Bros. Circus. In 1961 they were on Ringling International on a South American tour. At other times some of the animals were on King Bros. (Benny Cristiani Unit) and other shows.

The tickets have not been used, and are unsigned (not valid). Five are consecutively numbered. They have been in the plastic sleeves for years, being part of a collection which was liquidated about 4 years ago and probably originally acquired at a flea market (each envelope is priced) in the late fifties or early 60's.
