This stamp is one which allows advertising on
the spaces between the stamps. It shows an antique map of Hungary with
a sundial compass in two positions. While the map is unidentified,
several features on the map can be identified. On the left stamp
Budapest is to the left of the adjustable leg on the compass; the
thick black line is Lake Balaton, and the north-south river is the
Danube. On the right stamp the north-south river and then at 45° to
the corner is the Tisza River; the east-west river half-way down the
stamp is the Körös River.
The compass is a sundial compass with the gnomon folded
down. On a plate on the upper edge of the compass is “WEST London,” a
maker of such compasses.
