The Wish You Were Here Side . . . by David Moore.
I was recently sent a post card of the swing aqueduct at Barton. When I first saw it, my immediate reaction was that I had already got the card in my collection and it was some time before I got around to placing it in the album.
It was then that I discovered that the pictures were indeed the same and by the same publisher, but that the one I already has was an undivided back and the new one was with the divided back as we still use today. My original was posted in 1903, so it was printed some time before as the divided back came into use in 1902.
The new card was a reprint of the original negative done after 1903 and the publisher had taken the opportunity to bring the card up to date with the added correspondence space.
