Most B&R cards are illustrations with the logo on the address side. Later cards (1930s-) include the BEGRO series which still used the B&R logo but in a small circle rather than a wavy square or shield. "Begro" was also used as a logo on the picture side of some real photo cards, which have the BR logo on the address side.
