David & Gina Papazian, owners of the DZian Gallery at 65 Water Street in Worcester, recently expanded their horizons. They exhibited the paintings of Thomas Arvid at the Boston Wine Expo last month. The artist was on hand painting live in their booth, and from reports they did quite well. Arvid is known for his “winescapes”. His originals are priced in the $35-$100,000 range.
