100th Anniversary of the First Planetarium Projector, FDC

The stamp commemorates 100 years since the worlds first planetarium projector was introduced. The first official public event was at the Deutsches Museum in Munich on October 21, 1923. My flatbed scanner could not capture the metallic foil finish on the stamp. But it is much more apparent in this image taken with my phone.
