PRESS PHOTO BY DANA GRUBB Eric Kaczynski, a portrait artist from Allentown, takes advantage of warmer sunny weather April 12 to set up on Historic Main Street and work on a project. Kaczynski said he was visiting his mother, who lives in Bethlehem's center city, and couldn't miss the opportunity such a day provided. He uses charcoal mixed with pastels to give his work a 3D style.
