I was looking at the reverse of the Iowa SQ today. I never noticed the "GRANT WOOD" below the image.


Even though he died more than 65 years ago, his design graces the coin - one of the nicer and (according to that other thread) more popular designs. You may know this work of his a bit better:

What cool things have you ever noticed on the SQs that you didn't notice at first glance?
