Hey, friendslist puzzlers, especially those who worked for Games Magazine in the '80s.

Tanga, a website I've pointed to in the past for the astonishingly low quality of some of its puzzles, had an interesting pair of puzzles today. Here's the "hard" one; the easy one looks identical but, cleverly, has a different solution. Even the hard one didn't take me long, though.

That's because I'd seen the puzzle before. In fact, it appears in the Games collection The Book of Sense and Nonsense Puzzles (see here; skip to page 9), (c) 1985, so it presumably appeared in Games somewhat earlier.

Question 1: did this guy Arnott ever work for Games? Did he write this crossword? (In the book, it's credited unhelpfully to Margot Seides, which someone clued me in several years ago is an anagram, enumeration "5 7".)

Question 2: anyone, especially anyone with a vested interest in this (e.g. a copyright holder), have thoughts on how to proceed? Because speaking as both a puzzler and an academic, there's pretty much nothing I hate more than plagiarism.
