Davy likes puzzles. Yeah, most of the ones he likes are kids' puzzles, but he had very little schooling, so you can do the math. Still, once he puts them together they look great framed and gracing the walls of our editorial offices. This one, made by the Somerville company, finds our hero striking a noble and thoughtful pose in Alamo Plaza, somewhere between the time Texas joined the Union and the plaza was paved to accommodate snowcone stands. Look close, and you'll spy pieces shaped like a bell, a saber and a flintlock pistol.
