I found a El Topo us one sheet folded. I bought it to flip it . Is it rare. Hard to say what it worth. Would you send it to auction?
Thanks, Martin
It depends really...
If you want to get the most of it and soon, then auctions is may the way to go. Just do your calculation and be ready to take a little risk
If you want to get the most of it but not in a hurry, than putting it on ebay with high price and throw offers is the way to go (but not sure it is very efficient and beware of Ebay thieves)
If you want to get something fair and quick sale, then selling it here or other places online at fair price.
If you collect posters, than a swap is also a great way to get what you always wanted
Good luck with the flip !
