BlueRose-1978 Stanley Mouse

The picture has something of this: card, text, bill, design, vector, decoration, graphic, invitation, picture frame, abstract, banner, symbol, vintage, retro, margin, image, template, sign.
Perhaps it’s a concert poster for the grateful dead with a blue rose in the middle of the band’s logo and the words, blues brothers, r r p r s, r s, and winterland.
