A partial label for John Kesson of 28 Diamond Street, Aberdeen, Scotland. I hope to find a complete example as it is a really nice design with various frames and artist's palette. The frame on the left has the name and address, and the frame on the right says 'Carver' and 'Gilder'. He traded from this address from 1881 to 1915 or later.
More information on this framemaker can be found on the National Portrait Gallery website - Directory of British Picture Framemakers
I'm making an assumption that this is from the Wanamaker Department stores. Lots of information on the internet about him and his stores.
