As ranted on Nudes in News thread, nudity in art is art and should not be a battleground for the few pinheads that think any portrayal of nudity is 'harmful' as manifested in the Alison Stinely exhibition debacle and the Manchester one-track PC curators.
The opposite is true here - what a good idea to represent naturism in painting. This elevates it to 'art' and lessens the prudery objections and most importantly gives an opportunity to communicate the positive side of naturism without the self-appointed prude police getting in the way.
