Christmas greeting from puzzle maker Carter Johnson, Darien, IL 2000. Plywood, interlocking, cut along color lines. Artist is Lisa Blowers. Carter does not sell his puzzles, preferring to give them away as gifts, Christmas greetings, etc. A wonderful way to make an impact! Recently, he has given some to terminally ill people who have found solace and relief in assembling them in their waning days. Thank you, Carter!
