This 18p Irish stamp, issued in 1983, honors Boomerang, one of Ireland’s most celebrated show jumping horses. Boomerang, ridden by Eddie Macken, gained international fame in the 1970s for his victories in major competitions, including the Hickstead Derby and multiple Nations Cup events. The design shows the horse in profile, with a smaller inset illustration of a rider clearing a fence, capturing his athleticism and prestige. Issued by Éire, this commemorative stamp highlights Ireland’s rich equestrian heritage and the global recognition of its champion horses. A fine thematic piece for collectors of equestrian, sports, and Irish stamps.
