k here's a long shot if ever there was one.
I have a painting (pic to follow) painted sometime in the 60's to late 70's
I think,
it contains an image of amongst others david bowie so could be later not sure ?...

it was painted by a 20 or so year old girl,who lived on abbeydale rd. she'd be about 55/65 now I reckon.
as far as I know she was a hippy type and painted quite a lot during that era.and of a similar type
the painting is of six or seven famous musicians, inc bowie,elvis, buddy holly,cher, and couple of others i can't name.
just their heads, each is a different colour (ie elvis is blue, cher red, buddy green )and they all merge in a slight vortex its very psychedelic, oil on board about 3ft sq.
just seeing if anyone knows of anyone who might fit the bill.
