Toto au tour d'Italie

hi! i once saw this movie when i was very young. my father brings it up from time to time. he says it is one of the funniest movies toto ever made. all i remember was that it was very funny at the time but i really cannot remember anything about it. i would like to buy a copy of it so i can watch it again. i am also sure my father would not mind seeing it after so many years. although it is a very old movie i am sure it is available for sale somewhere. i have searched all over for it but have not yet had any luck. does anyone know where i can buy it? i would prefer if it was in the original Italian language. DVD or VHS does not matter to me. thank you for your help.
