Plain black and white (Puzzle no. 2,222)
Disappointingly, Frank Lewis did not make anything special out of these puzzles: I can’t detect any themes, though the grids are nice.
So here’s no. 2,222 (click for PDF file), which was originally published in 1988. Back with no. 1,111 soon, and solutions for both on Monday.
