A Practical Approach to the Study of Eye-Sign (in Racing Pigeons) — R. Fleming

Eye-sign, reading the iris, circle of correlation and pupil to judge a pigeon's breeding and racing potential, is one of the most debated subjects in the sport. R. Fleming's book takes a practical, step-by-step approach to studying the eye, aimed at the working fancier rather than the theorist. Out of print and sought after by fanciers who use eye-sign in selecting and pairing their breeders.
