Rummaging through old artifacts at an antique sale can make you feel like an archeologist on a dig and every now and then you come across a true commodity. Well, that’s what happened to Greg Pack, 70, in Essex, England.

The elderly man was at a boot sale, searching for old clocks and came across a battered old box. His son, publisher Scott Patrick, tweeted the entire account of what happened next. Inside the mystery box were 100-year-old glass negatives, that piqued the interest of his father. Pack senior, a retired graphics artist, told ITV News that he had been, “working in print years ago,” and explained, “I used to work with negatives and these looked quite good.”

However, according to the former artist glass negatives fade quite easily, using a mixture of his photo knowledge and modern technology he found a way to restore the photos back to their former glory. Scroll down below to see how he revived these images!
