Dot Goodwin said she was in Camden’s city hall when Camden City Council was discussing the then-pending hospitality tax several years ago when she noticed something. “I looked around and said they needed a medallion on the wall,” said Goodwin, art director for the Downtown Camden Guild and member of the Artists’ Attic on Broad Street. Goodwin said while she was sitting in on the meeting, she saw a vision of what belonged behind the mayor’s chair.
