@pyrofuego,
Dali, at the end of his life, was signing blank pieces of Reeves paper and numbering them (as an edition). The unscrupulous printers, in collusion with Dali's family, ran some scribbledy lines (like A cy twombly painting) on litho stones and then ran editions of prints. The only thing youd have is an autogrph by a senile old man who didnt even know what he was doing.
A real, honest to goodness Dali PAINTING can be worth in the low millions. Therfore I ad to the surprise that it would be, seeing that it was not insured by the house.
Its a Dali poster or a Poster signed by Dali. either way, michaels is probably good enough
