It's easy to see why these sketch-ideas for ABC's logo were tossed, but it doesn't mean that they aren't fun to look at. Just one thought: what's with the logo that looks like Pink Floyd's "Dark Side of the Moon?"
The creator had this to say about how he came upon the logos:
"I found these vintage logo treatments in an old Kodak box in a storage room at ABC Television in New York five years ago. Some are from the Capital Cities era while others look like late 1960's to early 1970's. I compiled a one minute edit of the logos."
