don't know anything about the origin of this sculpture but I really like it. I found it on my friend's Raymond Boekelder's facebook page.
There is something about a portrait with the tongue extended that is at once rude and yet compelling. The tongue is built to come in and out. It has an important role in receiving nourishment for the body. (We learned in high school biology that digestion actually begins in the mouth and on your tongue.) The tongue is also the primary tool we use for communicating with each other whether talking or singing.
In James 3:4 in the Bible we read that the tongue is like the rudder of a ship. "And a small rudder makes a huge ship turn wherever the pilot chooses to go, even though the winds are strong."
The first time the tongue came out in one of my paintings, was with the letter licking painting. The working drawing is available here.
