After the war, Thomas Flannery worked as a free-lance cartoonist in New York, where his work regularly appeared in the Saturday Evening Post, Redbook, Look, Colliers, Good Housekeeping and Cosmopolitan.
In 1948 he joined the staff of the Lowell (Massachusetts) Sun where he served as a cartoonist for nine years. He moved to Baltimore and became the first editorial cartoonist for The Evening Sun in 1957. He was the cartoonist for the Baltimore Sun from 1972 until his retirement in 1988.
During his 31-year career, it is estimated that Thomas produced some 7,200 drawings for The Evening Sun and The Sun, many of which were subsequently deposited at the Johns Hopkins University's Eisenhower Library.
Tom died in 1999. Well done Tom.
