John Canning Studio is not an architectural design firm. They do decorative painting, gilding and plaster work, particularly for churches and theaters.
There are several firms in Atlanta that do traditional work. There is Historical Concepts (James Strickland, architect), Harrison Design, Howard Design Studio, William T. Baker, and Keith Summerour.Well, the "idiot" is right though. Mere link lists aren't allowed at Wikipedia, at least not in such a thematic article. Else we'd have "yellow pages" like articles all around. What I wanted to do is to create a seperate list, that's where we can put it in a table. Perhaps this weekend I'll have some leisure to do it.
Btw, article content at Wikipedia can always be restored via the history. Unless it's copyrighted material that was hard-deleted. This is the New Classical architects list prior to deletion.
As I said, I'll outsource it, so please don't revert again. You might get blocked from editing Wikipedia.
