Issued by the Republic of Austria in 1978, this 1.50 schilling stamp commemorates the International Congress of the Building and Wood Workers' Union. The design by A. Pilch features drafting tools — a compass and set square — symbolizing precision, craftsmanship, and unity in the construction trades. Behind them, an orange globe signifies international cooperation among workers. The strong geometric composition and industrial motif reflect Austria’s commitment to skilled labor and trade solidarity during the late 20th century.
