I have a very simple guarantee, if you are not happy with my pictures I will replace them or refund your money. I stand behind everything I do. This is a very small business and depends on word of mouth for a large percentage of the sales. If I didn't make everyone happy, I would soon have no business. I do all the work myself so I control the quality. When I first started out, I was not using archival processes. I have replaced all those prints for the people who bought them. I have had zero problems since then. I believe you treat them the way you would like to be treated. If you ever have a problem with one of my prints, just call me and I will make it right.
