Early 1860s Advertisements by GW Wilson offering Landscape CDVs?

[Edward McCann]

  

  Has anyone seen advertisements before 1867 for Mr Wilson's landscape CDVs?

  Earlier this year, I posted the acquisition of a watermarked 1862  carte by GWW of Peterborough Cathedral. The logo on the verso is the early one Mr Wilson used and the caption is hand written.Since then, I have found an additional dozen C-D-Vs of landscapes trimmed down from stereo slides issued before 1863. All have the early logo and hand written captions..

   There must be many examples of landscape cartes by Mr Wilson in fellow collections that fit that description? I'm trying to establish a date for their introduction.
