Among the earliest of KLM Airlines hand-painted souvenir Blue Delft, this is a house decanter, empty, marked #21 on the bottom, made in Holland.  Distillery mark on underside is Rynbende distilleries. PLEASE SEE PHOTOS THAT SHOWS IT IS COMPLETELY EMPTY. Among the 100+ souvenir house decanters from KLM, only the first 45 numbers have been filled by Rynbende.

#21 depicts Markt 47, Delft.

Decanter is in very good vintage condition. Normal handling marks, crazing for its age, no chips or cracks.
