A workman posing beside the carved head of a lamb. "These heads were carved in place from blocks of stone set rough-hewn . . . The four heads centered on the facades [of the tower] are the beasts of the Apocalypse who worshipped at the throne of the Lamb [Revelation]" (Glenn, E. Bruce. Bryn Athyn Cathedral: The Building of a Church. Bryn Athyn: Bryn Athyn Church, 1971. Photo caption, p. 110). The workman is identified as "George Milne" on the back of the postcard.
