I do find many Thomas Landseer etchings, engravings, and lithographs on the high end fine art market. His work is known but as you well know this sounds like a bit more unique piece than many. Bonhams has dealt with the most that I have found and while this one maybe subtly different, I do believe they would be the best place to get a formal appraisal. They are located internationally so they also are quite accessible. Here is one of his stags that came up in 2003. It is also an engraving and not an etching so it is apples and oranges but here are a few that they have seen.

I hope this is helpful. Again I would contact Bonhams or Michells for a fuller appraisal. Bonhams has many locations at the following link. Please find the closest office to phone and connect to their specialist for a fine Landseer print. This is the best way to narrow the value. http://www.bonhams.com/eur/menuLocations/
