CDV photographer ID from partial rear image

[Downcraig]

Greetings
I have a cut down carte de visite (CDV) photo of a ?x great uncle possibly Stevenson, possibly Liverpool. Does anyone recognise the partial design from the back and is able to tell me which photographic studio it may be from. Any other hints as to date etc would be very helpful. Thanks.

Very rarely were card designs exclusive to one photographer.
This looks probably 1890's.
Seeing the front might help.
Is there a reason for wanting to know who the photographer was?

Thanks for your response. No particular reason for knowing the studio - just curiosity and to possibly identify location. I attach the front though I don't think it will help much. The sitter is possibly one of my great great uncles Allan Stevenson, a master mariner from Liverpool - born Scotland 1853, died at sea off India in 1897

I would also suggest 1890's.
