Artist Mr Murals returned to Navigation Street to add to the iconic Black Sabbath mural.
He is in the process of adding an image of them from their farewell performance at Villa Park earlier this month.
Mr Murals, who has previously painted Ozzy in black and white, told the BBC: “This image is one of the last images of them together from the gig.
“I started it a couple of weeks ago but didn’t get to finish it in time. Since then, with Ozzy passing, it’s heartbreaking. “
The mural will be finished on Saturday, with Ozzy and Tony Iommi left to complete.
The artist said he would have finished the mural sooner, but had been inundated with fans wanting to stop and talk about the singer.
He said: “You can see how much he meant to people. There are people here from New Zealand this morning that still haven’t gone back since the gig. “
