This is the 15th year that the Concord Museum has held this event, and I’m honored that Tillie Lays an Egg has been selected to inspire one of the decorated trees. I’ll be at the museum—sitting by my tree—on December 4. However, the display runs from December 3 through January 2 and it’s worth visiting even if I’m not there! Go to the museum’s web site to find out more about this holiday tradition.
