Vintage Bulgarian Bird Thematic Postage Stamp Collection

This item consists of six vintage Bulgarian postage stamps featuring a variety of avian species, displayed in a protective philatelic mount. The collection includes diverse denominations and designs, such as a vertical format 1st (stotinka) stamp featuring a Dalmatian Pelican (Pelecanus crispus) and various horizontal formats including values of 2, 8, and 0.09. The stamps are printed using multi-color lithography or offset processes on perforated paper. Notable features include Cyrillic text reading 'НР БЪЛГАРИЯ' (People's Republic of Bulgaria) and 'BULGARIA' in Latin script on others, suggesting a manufacturing period likely between the 1960s and 1980s. Visually, the stamps appear in fine to very fine condition; most are used as evidenced by partial circular date stamps (cancels), while the 1st pelican stamp appears to be mint or CTO (Cancelled-to-Order). The color registration remains sharp across the subjects, which include geese, birds of prey, and water birds. The perforations appear mostly intact without significant tearing. This set represents a thematic topical collection popular among philatelists specializing in Eastern European ornithology.
