Painting-By-Number

Last night, twelve famous paintings were stolen from around the world. I've been called in to investigate, but I know nothing about the missing art. I asked my assistant to curate a list of contacts that would know best about each of the stolen paintings. He provided a list of phone numbers, and pointed me to a display of replicas. If only I could figure out who painted each work of art... Maybe our agency issued T9 phones can help crack this case?
