Cool things with wheels since 2006
There was a Wm.Kenngott (Stuttgart) who made cameras.http://www.earlyphotography.co.uk/site/entry_C572.html
It may be this guy.https://www.sciencephoto.com/keyword/kenngott
I don't see a signature on any of these pieces of art, and nothing that is out of the dinosaur and cave man genre, so I don't think it's this guy.
It's this guy who did seascapes, same signature https://www.ebth.com/items/2152299-original-seascape-by-kenngott in the lower right
Your right,same style.
