Thanks for these links, too, Jan! One of the links provided a pdf copy of copyright information, and I downloaded it, and then uploaded it into my Google Drive. So now I'll be armed with a clear picture of copyright FAQ's next time someone asks me to share a pattern that's out-of-print.
I'm rather curious to see what the McCalls booklet displays regarding its copyrights.
Well, that is IF my max bid of $20 wins the auction.
BTW, the booklet I'm after is:
