  Rotterdam-Maaskade 1 11.X.1924 Maaskade translates quay or warf to the River the Maas This cancellation is numberred 1 and according to the Dutch Academy of Philately one of three cancellations used in this postoffice. All three were used between 1 January 1923 and 31 October 1935. This one was cancellled 11 October 1924 at 5 PM. I couldn't find the exact location of the postoffice during that time. The Maaskade was bombed in the second Wold War on 14 May 1940. I found a picture taken in 1924, same year as my stamp was cancelled, but probably during summer:   Delcampe , Ebay
