Talk about snail mail! A postcard mailed in 1903 has finally made its way to its destination in Wales—121 years late. Found by employees at the Swansea Building Society, this century-old relic has everyone scratching their heads. Where has it been all this time, and who was Lydia Davies, the intended recipient? As the hunt for her descendants begins, this postcard is bringing a bit of history back to life, one delayed delivery at a time.
