I am currently aware of only four pictorials credited to John Fowler:
Jenny Sewell as Jenny in Fiesta 09-06, 1975-06.
Marie Harper as Gracie in Men Only 45-08, 1980-08.
Helle Kjaer in Mayfair 15-11, 1980-11.
Paula Callaghan in Mayfair 17-05, 1982-05.
Note the setting for Paula Callaghan's above set, particularly the cane chair, blue bath, and china leopard. That same cane chair, blue bath, and china leopard all also feature in a set of Karen Mifflin as Pippa in Knave 13-10, 1981-10, photog. Lewis Blood, see Cream Cheese
here.
So provisionally, John Fowler
may be an aka for Lewis Blood.
I currently know of only a few sets by Lewis Blood, though this may well grow once I start looking through Knaves.
Alice in Fiesta 15-09, 1981-09.
Matilda in Fiesta 16-07, 1982-07.
Karen Mifflin as Karen in Fiesta 17-13, 1983-Xmas.
Mandy Miller as Willa in Knave 12-12, 1980-12.
Mandy Miller as Willa in Knave 13-01, 1981-01.
Jo Peace as Wynne in Knave 13-13, 1981-Xmas.
Rachel Roberts as Tess in Knave 13-04, 1981-04 - & yes, I have
previously noted the presence of a bed frame in this set that resembles one used by Adam Cole.
