The stamp entitled "Summer Holidays" is the contribution of Germany to the international stamp series, which is initiated each year by the Association of European postal organizations.
The theme of this stamp is addressed to a time of summer holidays in Germany called "Hundstagsferien" ("dog-day holiday"). It lasts from 24 of July up to 24 of August. Its name doesn't come from some sweaty dogs in these supposedly hot summer days, but from Sirius, the Dog Star, which rises at this time period almost simultaneously to the sun.
