Each painting increased Monteriggioni's value, with the higher the price, the higher the added value. Paintings sold by art merchants changed depending on what region they were in. Once purchased, they could be viewed at the art gallery on the second floor of the Villa Auditore, while also providing some background information on the painting itself, and its artist. Art merchants weren't as common as blacksmiths or doctors, but there was at least one situated in each city.
