Part of a series city's signature dishes, this design features a Chicago drag-it-through-the-garden dog.  Fully functional as a coaster, but also a great little piece of art - these are the perfect gift. This design is perfect for travel buffs, foodies. • Red glass, printed in yellow enamel • 4" square, with rubber bumpons to protect surfaces • Handmade This coaster is screen printed, kiln formed glass. Each piece is made by artist Laurie Freivogel in her Oak Park studio.  She screen prints by hand each piece of cut glass with fine enamels, then fuses in a kiln.  Designs are permanently fused into the glass.
