Last year, I bought about 50lbs worth of old knitting magazines (mostly McCall's Needlework) at a flea market for two dollars. The patterns are all from the 50s and 60s, and I'm just getting around to finishing a TOO COOL sweater from Fall/Winter 1955-56. I'd love to share these patterns here, but I know I might be crossing the line with issues of copyright.
However, I don't know if this is the case with only recent patterns or all patterns ever to hold a copyright. These patterns are exclusive to the magazine, and are out of print (and have been for some time now!) and thus can't be bought new, so is copyright really an issue? The copyright would be detrimental to the aesthetic beauty and the existence of the patterns themselves because it would mean that they'd only be "legal" in the original form, and because they can no longer be bought except by chance in a lot, it would essentially wipe them out of existence.
What do you think about the legality of sharing vintage patterns freely?
