Talk of cask-matured drawings, this magazine Linus from 1970 (Eds. Frank Dickens and Ralph Steadman, publ. Milano Libri Edizioni) got me switched on to ‘serious’ cartoons as a teenager. It opens with Ralph Steadman:

Here was my first encounter with Jean-Jacques SempéWindsor McKay‘s Little Nemo, George Herriman‘s Krazy Kat, Topor, Fellini the cartoonist, and the Upside-Downs of Little Lady Lovekins and Old Man Muffaroo by Gustave Verbeek;  not to mention Charles Schulz and others familiar from Punch magazine – ffolkes, Bill Tidy, Larry

Michael Bateman’s introduction indicates how far things had to go with Taking Cartoons Seriously in the UK:
“It’s surprising that there has never been a serious magazine devoted entirely to all aspects of cartooning in this country. It’s not as if cartoons aren’t liked …The world readership of cartoons is immense…. Americans know their cartooning birthright, and even study cartoon history in universities….It’s almost impossible in this country to see the work of good European cartoonists and illustrators.” He concludes: “For anyone hooked on cartooning, as I am, Linus is a nice wrapper for all the cartoons you’d like to have been able to see and never could.”
I have not seen another wrapper like it since. Was this the only edition?
