This is a pair of original glossy black & white/sepia postcards (size approx 3½" x 5½") published by Nels and Uitgave Best in the 1940s/50s (?). Both feature views of Keyserlei/Avenue de Keyser with the Central Railway Station prominent; plenty of trams and contemporary cars & trucks complete the scenes. 

• The cards are both in very good pre-owned condition with minimal signs of handling; they're unmarked and postally unused and will be sent in a card-backed envelope for added protection.
