Souvenir sheet

Souvenir sheets are small special format little panes of a few stamps, once only produced for special events. That event would often be a major stamp exhibition. Today, many stamp sets have souvenir sheets added as a normal thing.

They typically have large margins with inscriptions and details about the event. The stamp design can be part of the overall design of the souvenir sheet. Varieties can exist with differing margin imprints for different events.

Souvenir sheets are generally postally valid since, after all, they are sold by post offices. If produced imperf, souvenir sheets can be a source of imperf singles of the stamps used. However, sometimes only the intact souvenir sheet is postally valid.

Printed souvenir items produced for events, either by the post office or privately, should not be confused with souvenir sheets.

There are also private souvenir items that have reproduced expensive Chinese stamps but in a different size or perf.  File:US Magic SS.jpg|US magic souvenir sheet, created in lenticular lens format
