In the early 1950s, Earl Mac Pherson
was turning out not only a yearly 12-image calendar for
Shaw-Barton, but numerous other pin-ups on playing cards,
greeting cards, posters, matchbook covers, books, the entire
panoply of pin-up merchandising. He took on Jerry Thompson
as an assistant, and they worked together in California.
The hardy Mac Pherson somehow came down with polio and,
for a time, Thompson approached the level of "ghost." When
Mac fully recovered and got back into the pin-up swing,
he sold Thompson's contract to another publisher, and from
1952 until at least 1958, T.N. Thompson's "Studio Sketches"
was a top-selling rival calendar.
Thompson not only worked in Mac's sketchbook style (although
eschewing pastels for oil), he used photo reference of Mintahoia
D'Roney and other Mac Pherson models. His earlier calendars
are quite good; later an overt cartooniness crept in as
he moved away from Mac Pherson's influence.
