Ta-Da...Acqui Terme is correct! Sorry Gerd but 4popoid has arrived just before you...even if he wrote the name with a little typing mistake.
I live in Acqui Terme and I discovered that the Grand Hotel Terme held a beautiful Concours d'Elegance in 1933, 1934, 1935 and 1936. This picture, and another one I found in an old Photo Shop, comes from 1934. This car belonged to a certain Mr.Ferraguti who lived in Hotel S.Marco.
