looking at architecture on engraved stamps. Here's a lovely Swedish stamp, issued in 2010 (Facit 2759). One of a set of Swedish castles, it depicts Läckö Castle, one of Western Sweden's most important buildings. Dating originally from the Middle Ages, but much altered over the centuries, Läckö is now a famous masterpiece of the Baroque style. The engraver of the stamp is Lars Sjööblom - there's more information on him below the image.
