Bulgaria Postal Stationery

Bulgaria · 1900 ·

This is a general category for Bulgarian postal stationery, which includes items like stamped envelopes, postal cards, and aerogrammes. These items are sold with the postage pre-printed on them, eliminating the need for a separate adhesive stamp.

Postal stationery has been an integral part of Bulgaria's postal system since the late 19th century, evolving with the country's political and social changes.
