I have 3 different Blue Guides to regions of Italy:
Northern Italy (including Venice, Milan, Bologna);
Tuscany;
Florence.
These are classic guides which have basic travel info, no large colored photos, but exhaustive info on the art and architecture of each region, including everything from small country churches to room by room tours of museums. The most detailed of any guide I’ve used. These 3 books are in excellent condition, without markings or broken spines. Asking $10 for Florence, $15 for Tuscany, $20 for Northern Italy, would consider a discount for multiple. Cash in person only.
Also have a large illustrated book by Cardini, “Tuscany”, covering landscape, history and art, for $15.
I live in a gated community at Marina Bay, just off 580 between El Cerrito and Pt. Richmond.
