Having read the first book about celluloid toys I wanted to go further and purchased this one.I was particularly interested in the information abiut celluloid itself, its mainteance and repair. The author is a plastics expert and lends valuable insight into the celluloid material. Excellent photos and descriptions throughout the book. Down side - most feautured items are at the high end of collecting and more rare than those in the first book. Still a must for the serious collector.
