I have a set of Haunted Mansion stretch portraits for sale. They are 21" wide and 36" tall. I am sure you could take a high res photo of them and then print to your plotter. Selling the set for $150.00.
Have you asked the guys at doombuggies.com?I'm looking to recreate the portrait props that are found within Disney's Haunted Mansion. I own an oversized plotter that prints up to 5 ft. wide, and I would be printing either on opaque substrate or backlit material (for you techies out there).
My hopes would be to find the various Changing Portraits, including "Master Gracey"
the Four Stretching Portraits
and the "Family Portraits" that appear in the Gallery of Doors:
I've been looking around and buying books trying to find high-resolution imagery of the portraits, but most everything is just not usable. Ideally, a book should have page-sized images with magazine-quality printing (that is, the dots of the halftone or screens are so fine you can't see the dots), or else high resolution scans of the pictures that are meant for oversized printing (300 dpi - the bigger the image size the better).
I know this is probably a bunch of techno mumbo jumbo to many of you, so I'll be happy to look at any leads if you're not sure of the specifics. Thanks in advance.
