Jim Flora was wonderful magazine and record cover illustrator from the mid-20th century. (The Mischievous Art of Jim Flora is a great intro to his work)
Here’s one of his illustrations that I hadn’t seen before.
Karramarro says: “Yesterday I found a LIFE magazine in Spanish from 1960 with a double page illustration by Jim Flora. The text is really funny, about how will be the future in 1975. With mail sent by rockets, mechanic stairs in the cities, plastic organs for transplants etc. The illustration is really nice, and I have just uploaded a flickr set with closeups.”
