A coworker of mine lent me a bootleg VHS of Star Wars purchased by his father in 1978 from a porn store. The colors are vibrant and the picture quality is excellent (for a VHS, that is). It's very well preserved and is on a RCA VK250 Premium Quality Video Cassette, which was popular in the late '70s.
The following images don't do it justice, as they're of a 10" CRT TV and taken with a mobile phone.
The following two images are of the RCA VK250.
I purchased a high-end VHS-to-DVD converter today to get this out to OTers ASAP. Is anyone interested?
