Large mix of Czech stamps dating from post-WWII (unused sets of the fist two series are in here) until 1960. This is a huge collection of duplicates from my son's assembling of a comprehensive collection by purchasing sets and lots. There are probably about 700 or so stamps here, including many complete sets (some duplicated), also many partial sets, and all either MNH or CTO. A number of se-tenants as well. All stamps sound. Some are lightly hinged.
