The artist spent all his working life from 14 years old - except for a period as a driver in the Second World War - as a National Coal Board painter and decorator around Barnsley mines.
Born in North Yorkshire in 1921, he moved with his family to Royston as a boy and later lived in Ryhill.
Eric died last year and bequeathed more than 400 unframed works to his framer - four of which have been donated for the auction at the Cooper Gallery’s Sadler Room.
Coun Robert Frost, cabinet spokesperson for place, said: “The Cooper collection is well regarded and a real asset to the borough, the money raised will help conserve artwork to be enjoyed and appreciated by generations to come.”
More than 80 pieces of work from artists including Graham Ibbeson, Malcolm Whittaker, Julie Pratt and Jan Barnsley feature, and there will also be a raffle.
It takes place tonight from 6pm.
