The original magazine cover for this piece "A Man...A Woman...and 1968's Most Terrifying Survival Siege"
Born to Polish and Austrian parents of Jewish heritage in Brooklyn in 1927, Kunstler is still alive as of this post (96 years old). His work in Stag magazines and pulp fiction paved the way for later historical and movie poster art (including The Posedon Adventure). It ranged from chauvinistic, salacious, exciting, violent to utterly absurd (see the Pangolin attack below) but with an undeniable flair for composition and storytelling.
Wow, I love this and all the other art of his you've posted in this thread! Thanks for posting!
By the way, I want you to know that you're one of my favorite posters on Lemmy/the fediverse as a whole! I appreciate you, the sources and information you add, and all the work you put into these posts. I sincerely thank you! They bring much-needed bright spots to my day pretty frequently :)
