Czechoslovakian Postage Stamps, Cancelled-to-Order (CTO)

Czechoslovakia · 1965 · Various

This is a collection of Cancelled-to-Order (CTO) postage stamps from Czechoslovakia. CTOs are stamps that have been cancelled by a postal authority but were never used for postage, intended for sale directly to collectors. They typically feature a clean, well-placed cancellation and retain their original gum.

Czechoslovakia produced a wide variety of stamps throughout its existence (1918-1992), and CTOs were a common way for the state to generate revenue from the international philatelic market.
