This image is from Robin Alston's collection of contact transparencies that
he made for the materials ultimately published in Fredeman,
A Rossetti Cabinet
. This particular image did not appear in Fredeman's book, however.
For whom this design was made is uncertain, though it almost certainly
belongs to the early 1860s, and probaby after the establishment of
“the firm” of Morris, Marshall, Faulkner & Co.
