Great concept but flawed execution. Some of the occupations are really hobbies. Some are a real stretch. Xenologist? Vibraphonist? But the main issue with this alphabet book is the lack of definitions for the jobs listed. Even the "Want Ads" in the back of the book are full of puns, but lack any actual job descriptions. 
 To compound this confusion, the illustrations don't always provide enough visual clues to clarify what the occupations are. For example, the K-9 Officer doesn't wear a police uniform. The Umpire page contains three people: a batter, a catcher, and an umpire - and doesn't specify which is the umpire. The Ringmaster stares at a caravan of animal cages, but how is his job different from the Zookeeper? 
 Unfortunately, this alphabet book of occupations misses the mark.
