Here are ‘before’ photographs of houses saved by Historic Salisbury Foundation in years past. As part of celebrating its 40th anniversary year, HSF has been conducting monthly contests, asking Post readers to identify the names and locations of the houses pictured. The ‘after’ photos and answers for these same houses will appear on this page next week. Here’s one extra question for the house on the trailer being prepared for a move — where is it currently located? Email your answers to volunteer@historicsalisbury.org, or contact Barb Sorel at 704-797-8931. Toward the end of the year, HSF will award a prize to the person with the most correct answers to the monthly before-after contests.
