I’ve been talking about this concept for a while (most recently in the Penn Gazette, my alumni magazine), and have even created a few myself; the WNYC Bored and Brilliant campaign also made some. I like the homemade quality and whimsy of Molly's, though. Not that they actually are necessarily that easy to make. This has that improved look that I suspect takes hours to get right.
This one could be the cover of my next book, on rest.
I especially like this one because Mom just got a new smartphone, and is calling me regularly for tech support help.
