As "Gilligan Newton-John" comments on this PARADE MAGAZINE Retrospace blog entry:
" … Parade is densely packed with super seventies-ness: a must read for any 70sphile. Enjoy!"
And it is. Do take a look. And there are also three cartoons (by George Dole, Al Ross and Chon Day) on the page with Joan Rivers jokes. ("I try to stay young. Last week Edgar told me to act my age. I did and he called an ambulance.") I nicked the page above.
