This 3 Heller stamp from Austria, issued in 1910, forms part of the celebrated Franz Joseph 60th Jubilee series, marking six decades of the Emperor’s reign. The design features a finely engraved profile of Emperor Joseph II, reflecting Austria’s historical lineage and the artistic style of the Secessionist period. Printed in a deep reddish-violet shade, the stamp displays elegant ornamental detailing typical of Koloman Moser’s design work.
The lower margin shows Kolo Moser (designer) and F. Schirnböck (engraver), both key figures in early 20th-century Austrian philately. Used examples like yours, with clear portrait detail and strong colour, remain desirable among collectors of classic Austro-Hungarian issues.
