Are there any comparable catalogs out there for post WW2 cancels?
Answer There is no price guide available for post war A.P.O. cancels. The zip code era with 5 digit numbers stared in 1965. In general, they are much scarcer than war time cancels, which is logical as there are far fewer soldiers. Demand is not strong. Cancels from large bases in places like Germany, England and Japan are inexpensive. Cancels from smaller places are a bit better.
