Here are this month’s “before” photographs of two houses that have been saved by Historic Salisbury Foundation over its first 40 years. Do you know the names of these houses and where they are located? Submit your answers by email to volunteer@historicsalisbury.org, or call the foundation office at 704-636-0103 by Thursday. Be sure to include your name. Each month, as part of its 40th anniversary year, HSF is holding a before-after contest. Next week, “after” pictures of how these homes look today will appear on this same page with the answers to today’s questions. At the end of the year, HSF will be giving a prize to the person with the most correct answers over the year.
