What would you say is the most expensive Disneyland souvenier item from the past? Some things that come to mind would be, 1). the 1958 Disneyland map with the Viewliner Train on it 2). the electrical (Schuco I think) Monorail train set 3). a paper item with Walt's signature on it 4). the plastic helmet with all the "lands" on it 5). an original opening day Disneyland ticket. Any other ideas?
