About the artist UL GUIDI I found something on the sites:
http://www.invaluable.com/auction-lo...1-c-2y9x9zpypq
and
http://www.liveauctioneers.com/item/2626636
The second is even a reproduction of two of his paintings, on the plot and design (too sumptuous, in my opinion) like yours - I brought them in the appendix. And who is this particular UL GUIDI, will be hard to find: GUIDI a very common surname in Italy, and Your UL GUIDI, apparently, not very well known. Good luck in search!
