Any ideas where my ancestor's picture was published?

[GuyMassey]

Years ago I was sent poor quality line engraved picture of my ancestor John James Thornhill 1764-1857. He was a Cutler and traded from 144 New Bond Street, London.
I have been trying to find out what publication it appeared in ever since in the hope that I can obtain a copy in context.
Any help or ideas where to look would be most welcome, or maybe someone can succeed where I have failed!
The business was taken over by his son Walter when he retired, and was a supplier of chatelaines and other goods to Queen Victoria.

A probable shot in the dark, but have you had a look at the book mentioned in the bibliography here https://www.britishmuseum.org/collection/term/BIOG80040? (John Culme, 'The Directory of Gold & Silversmiths 1838-1914', Woodbridge 1987)

Thank you for the suggestion, but no luck there unfortunately.

Hi,
There's a tree on Ancestry that has the same photo ( but cropped,  ie without  the surrounding frame  that you have in your pic) ,which was " originally "shared  by the tree owner way back on 8 May 2014.
If this isn't  your tree(?) , maybe the tree owner could  tell  you where she aquired it from . Tree is owned by a Humphries

Then there's  another tree , which the pic is  exactly like yours  ( with the whole surrounding frame like yours) ,and this was shared 2 years later ( tree owner  MCmctallen80)  in 2016 b( so maybe not copied from the first tree as it has the  frame, unlike the first  one in 2014) , maybe they have both independently found  a picture of him. (Also there is another  tree in 2019, but I assume this was copied from the tree in 2016 tree -( as has same frame)

If either of the trees aren't  yours, ( especially the oldest shared  one  in 2014, without the  frame ) maybe they can tell you where they aquired the photo,  both owners are active/ signed  in within the past few days
Kind regards
