Video game themed illustration circa 1982

This is an original video game themed ink and watercolor illustration circa 1982 featuring a nuclear family gathered around the television playing an Atari-like gaming system, while a horrified Grandpa looks on. The piece is signed McIntosh in the lower left; in spite of the spelling difference, it may be the work of illustrator and cartoonist Craig MacInstosh as it resembles his political cartoon work.

The style of the piece os very much in keeping with illustrations done for the pioneering video game magazine Electronic Games in the early 80's. I need to research further to find exact place of publication.
