Hamilton Wood Type and Printing Museum in Two Rivers, WI. They are on exhibition at the Hatch Show Print’s Haley Gallery in Nashville, TN from September 6 to November 11, 2014.
Here's what the website says about the work:
Each Letterbug ™ is hand-printed using type manufactured by Hamilton and is part of that museum's collection of over 1.5 million pieces of wood type; the fine details completing each print come from much smaller metal type, or hand-inking, by Bill, creating unique effects on every print. The prints are an homage to the unique strata that insects and type occupy in their respective kingdoms.
And about the artist:
