Query: Tops as a Coca-Cola reference!

This volume is a super reference for a wide range of Coke collectibles. Has been upgraded with more color photographs and the prices reflect the current market. Lots of additional information helping novice and expert collectors know what is authentic and what is not. There are a number of Coke memorabilia reference books out there, but Petretti's is the most thorough and professionally done.
