KLM started issuing miniature house bottles in 1952 to their customers. In the 1980's Bols provided these little house bottles to KLM.
Offered is #58 which represents a house built in 1625 in Amsterdam with the address Herengracht-101. The number is incised on the bottom and in blue on the back. Excellent condition.
I have many of these, so if you are looking for a particular one, feel free to contact me.
