Attractive poster stamp issued by the Stockholm Postmuseum in 1981.
Booklets were produced containing 10 of these souvenir stamps, but they appear to have had no postal validity. The price quoted here is for one stamp.
“Grundat 1906” refers to the year that the museum was set up; “grundat” is Swedish for “founded”.
