Your looking at some of Eric Gurney's earliest work as a freelance illustrator.
Gurney, who grew up in Toronto, Ontario, not an hour from where I sit as I type this, left home in 1938 to work for Walt Disney studios in California.
Ten years later he was in New York City, represented by Lester Rossin - the same agency that also repped David Stone Martin - and this December 1948 ad for Proctor was undoubtably one of his first assignments.
Gurney, who won the 'Best in Advertising and Illustration' award from the National Cartoonists Society in 1961 and again in 1971, went on to both write and illustrate children's books which, as he says in his NCS bio, "sold in the millions."
