This is a one of a kind, test run plaque, based on the plaque that will be used in Disney's "Haunted Mansion Parlor". The bar looks like it's gonna be AMAZING!! This is a one off piece (not official Disney merch), to check for accuracy and detail.
There are lots of pictures of the full-size Plaque from when Disney made the announcement, just search for "haunted mansion parlor" and you can come up with lots of pictures to compare this one for accuracy. It's about 8 tall and was hand painted and aged. Once it's gone, it's gone.
