Issued by Montserrat, this vibrant 35-cent commemorative celebrates the bicentenary of mankind’s first successful balloon ascent by the Montgolfier brothers in 1783. The stamp features an ornate hot-air balloon with classical sun motifs and royal emblems, reflecting early European aeronautical artistry. The bold “SPECIMEN” overprint marks it as an official reference example, adding special collector interest. Part of the popular aviation and flight-history thematic series, it appeals strongly to aerophilately and transportation collectors. Clean design, bright colours, and historic subject make it an attractive exhibition piece for flight or science themes.
