She looks at it over my shoulder, and says to me, "Is that Cubist?"
I smiled at her politely and said "no," slightly embarrassed, and hoping not to have to admit that it's actually just a kid's comic from the '60s.
But, like the old-school New Yorker that she is, she's persistent, and asks to see the image again. So I hold it up for her and she stares at it for a good 15 seconds.
Finally, she concludes, "Well, it looks like Picasso to me."
To which I replied, "No, it's Jack Kirby. He's far better."
