The lighting is terrible (my walls aren't really puke-yellow!).
The Star Wars banner is approximately 4 feet long by 1-1/2 feet high and made of stiff vinyl. I bought it off ebay probably 10 years ago and have just now gotten around to framing and hanging it. The banner's true origins are unknown but I suspect it was part of an in-store toy display; the style of the logo makes me think it was the Micro Machines line, probably late 90's / early 2000's.
