I've just made a scan of the vinyl album cover of A Night At The Opera and isolated the two faeries. You can find the two images on my site (see below) under the menu Backchat - Paintings and Drawings. At the bottom of that page.
They're in PNG format so there's no background color, just the faeries. I've corrected the green one's wings a bit because they're behind the lion's leg in the original drawing.
Hope this will do.
