Another book I bought a year or two ago that has been jumping off the shelves recently is
" The Mischievous Art of Jim Flora" - Flora (1914-1998) was an American illustrator and artist responsible for dozens of jazz sleeves in the 40's and 50's. Such as "Mambo for Cats":
And this "Collaboration" piece that uses conjoined twins - there are just not enough conjoined twin illustrations out there? His work was clearly a big influence on U.S. illustrators Gary Baseman and Tim Biskup, I don't know if Benoit Jacques knew of him but this cutaway ship one of Flora's later works from the 80's really reminds me of Benoit Jacques', whose work I love - I do like cutaway images for some reason? I have added a link to the Jim Flora website through the title. Have a look?
