WP1973R WPG - SITTING ROOM - C.P.R. STATION (REVERSE)

This is the reverse of WP1973 by L.J. De Nobele. It was apparently used as an advertising card by a company in Belgium where, it is believed, De Nobele had his cards printed.

This one could be mailed out to customers - as the address side is blank. I have another De Noble card where the entire back was imprinted with some sort of advertising for the "Sabot D'Or" store in Belgium. It may have been used as a handbill since it could not be addressed/posted.
