I wouldn't argue that, for most of the paintings he made to put into books. But you could also point to a couple dozen that were definitely
not crappy (none of them are abstract). Unfortunately he was also happy to produce junk like the one in this thread. It's
really difficult to make 26 (or 86 or 159) little paintings all at once, and that's how he did these. All in a day or two, on a deadline.
According to Krumhansl, he made
more than a thousand paintings for BSP books:
63 - THE DAYS RUN AWAY LIKE WILD HORSES OVER THE HILLS
60 - POST OFFICE
85 - FACTOTUM
54 - SCARLET
86 - LOVE IS A DOG FROM HELL
91 - WOMEN
116 - DANGLING IN THE TOURNEFORTIA
148 - HAM ON RYE (101 numbered, 47 lettered)
159 - HOT WATER MUSIC (126 numbered, 33 lettered)
149 - WAR ALL THE TIME (101 numbered, 48 lettered)
Looking at those numbers, I can see why he refused to do any more after 1984.
