I am selling some Disneyland / Walt Disney World signs on eBay. Most are plexiglass or plastic. Most likely they were displayed on lamp posts on Main Street or elsewhere in the parks. Please search for "Disney sign" or "disneyland sign" to find the auctions. My username is broncofan1970.
Here is a link to one of the signs as an example: http://cgi.ebay.com/ws/eBayISAPI.dll...MESE:IT&ih=014
