As someone who has been lucky enough to visit Disneyland for many years, I've got a whole bunch of D-Land related merchadise and souvenirs.
Some of my favorites are:
Haunted Mansion LP with that gorgeous art book
Pirates of the Caribbean "making of" book (not the current one, but the magazine sized one from the 70's)
Randotti Haunted Mansion gravestones
Little hinged attraction houses from the mid-90's
Haunted Mansion T-shirt with Mickey terrified by Hitchhiking ghost
What are yours?
