1971 Iran International Wetland and Waterfowl Conference Stamp Set

This is a collection of philatelic specimens from Iran, specifically commemorating the International Wetland and Waterfowl Conference held in Ramsar in 1971. The image shows three primary stamps with denominations of 1R (Rial), 2R, and 8R. The stamps feature detailed illustrations of waterfowl: a Smew (1R), a Ruddy Shelduck (2R), and a Greater Flamingo (8R) in their natural wetland habitats. Each stamp includes bilingual inscriptions in Persian script and English, noting 'IRAN' and the conference title. The printing utilizes a multi-color lithographic or photogravure process on perforated white stamp paper. The 1R and 2R stamps are horizontally oriented, while the 8R stamp is vertically oriented. Condition-wise, the stamps appear to be in unused or 'mint' condition with crisp, intact perforations and vibrant color preservation. There are no visible signs of heavy cancellation marks, foxing, or significant creasing. Below these, partial images of other ornithology-themed stamps from different jurisdictions (labeled in 'Fils') suggest these are part of a larger thematic collection. The set is significant as it celebrates the historic Ramsar Convention, the first modern global intergovernmental treaty on conservation.
