The original Acrobats of the Air (1933) was one of the first comprehensive treatises on the age-old hobby of breeding and flying Roller pigeons. This 2015 edition consolidates material contained in the 1933, 1941, and 1944 editions of that book, and also includes much later correspondence with the main author not previously published. As such, it provides access to obscure resource material for contemporary students of the history of the breed.
