Have you looked through =������.

 Perhaps you are after this postcard?

"I've seen a black and white picture in one of the restaurants of people sitting in the piazza but I can't seem to find where to buy it."  These days - there's no need to scan or photocopy the picture - just take a digital photo of it, and then use your computer to make a decent sized print.  All you need is a 6Meg camera or higher If you want a print bigger than A4 [or A3 if your printer will do that], take the camera to a 'Print Shop' -  in the UK they will enlarge the print to almost any size you want.  .

You could of course just download one of the pictures in Alan h's link and just print it out in the meantime.  A bonus.   You could also use the image as a wallpaper on your computer.
