This is a very old used colour postcard of Main Street from E, Killin, posted sometime around 1911-1920, the date in the postmark is not clear, but the card still has the King George V halfpenny stamp attached. It is a V&S Ltd Post Card, by P Ross, Killin, numbered 71525jv, and the card is in very good condition – no creases (other than to some corners) or obvious marks. The lines in the sky are odd – they are not creases and appear to be integral to the printing of the original postcard.
