This is a collection of old images of Wales that give a glimpse as to what life was life in Llangollen, Denbigh and beyond 100 years ago - and, of all the places, the images turned up in the U.S, in the archives of the Library of Congress in Washington.
check out this link for the whole story. Make sure you check the links on the page as they link to Flicker where the Welsh photos from the Library of Congress have been placed. 6,882 I think although I have not checked all of them. :)
