Thanks for sending the card -- it is a nice one. My apologies for taking so long to get back to you.
The image you sent is familiar to me, but I did not have it iis not in the RIC collection. The print started out as a 1/2 of a stereoview that was trimmed to fit the cdv format. The number on that cdv will match the number on the original stereoview.
As you know, Bedford travelled extensively in the early - mid 1860's. He often took his 2 kids and his wife who posed in his photos to help animate a scene. He did the same with his carriage and there are quite a few views (mostly stereoviews) with the carriage strategically placed to add depth, provide scale and/or enliven the photograph.
I think GWW is still somewhat underrated due the volume of reproduction. I think time will raise his stature further. I have a similar number of images to yourself, mostly stereos and cdvs but also some larger albumen prints, I've even added a few of the late GWW postcards to my collection.
I have been working on a very large digital stereo card index database. (you cant buy them all!)
I think I may have been a little over keen in my attribution of the cdv image i posted, but the images is still very fine and one of my favorites.
