It's unfortunate that this retro brochure for Castle Dracula in Niagara Falls, Ontario doesn't use any actual photographs of the attraction. If you Google "Castle Dracula Niagara Falls" use can see it's actually fairly impressive looking (at least from the outside).
UPDATE: I've just discovered that the artwork for this brochure was lifted from a 1973 issue of the House of Mystery. Check out this post over at The Haunted Closet. Looks like you're busted Castle Dracula people.
