For Trick-or-Treating Philatelists

A full sheet of 15 stamps that make up the squares of a chocolate bar. They're Swiss, they came out in 2001, and they're scratch-and-sniff. (The stamps only smell like chocolate; they taste like plain old stamp glue.) I mounted the stamps on cardstock with photo corners that look like pieces of chocolate.

By the way, in 2007, the Year of the Pig, China put out this scratch-and-sniff stamp bearing the aroma of sweet-and-sour pork.
