Went to pick up my photos from the fair today and there was a business card attached to my paperwork. There was a note written on the back asking me to contact them, so I did.
The guy just wrote back and said he wanted to buy a copy of my merry go round pix!! He hadn't done so at the fair because he would have had to drive about 3 hours back into town today in order to pick it up.
Very happy to now have met my goal of selling at least one image to someone I don't know.
