cover 1878 (8 Nov.) printed "JOHN SANGER & SONS CIRCUS & MENAGERIE" envelope, showing on the front (printed in black): the circus troupe procession with various wild and exotic animals, and on the reverse (printed in mauve): the "Lord Mayor Procession", used from Barking to Drury Lane and bearing 1864-79 1d. plate 210; a few very minor faults do not detract from this beautiful item.
