Martian Manhunter & Justice League Logo Signs

Here's an oddity I stumbled upon on the net: Mary Ann Nelson McAlister, a fellow Texan (and possibly even another Jew, b'gosh,) made signs relating to our favorite Martian out of wood and acrylic. What would possess her to recreate the Martian Manhunter logo, of all things, is a mystery to me. I suppose an email would clear that all up, but nah. I prefer idle speculation and minimal human contact. Those inclined to explore further can check out her extensive artwork in a variety of mediums at Mary Ann Art.
