They say there are no stupid questions, only stupid answers. So here’s my stupid answer:
It’s completely worthless - I’ll take it off your hands and dispose of it for you.
Real question though… who is it signed by?
Frank Miller. It’s so big we can’t even hang it on our walls. And was never hanged so no tape marks or pin holes or anything.
Oh wow. I can’t actually help you with your question, but that is legitimately awesome!
If it was regular size I would just put it in a case. But it’s in mint condition no creases or marks or anything. And has brass holes if you want to hang it but hard to find an 8 foot case. I think it was made for a movie theater.
Have you tried using Google Lens? It does a decent job of getting a basic idea of the value. I use it at thrift stores all the time to check prices. Not sure how well it will work for something that unique
