Give me a museum and I'll fill it.

This line is very widely credited to Picasso in both English and French ("Donnez-moi un musée et je le remplirai"), and it captures something genuine about an artist so prolific he produced tens of thousands of works — but we could not trace it to any primary source in Picasso's own writings, speeches, or a documented interview. No book, speech reprint, or newspaper from his lifetime records him saying it. Even reputable references treat it as an undated saying rather than a sourced quotation; Encyclopædia Universalis, for instance, invokes it as a challenge Picasso "launched one day," noting how fittingly it was answered by the 1985 posthumous opening of the Musée Picasso in Paris. Notably, the one book-level citation circulating online (the 2000 volume *I is Style*) does not support this quote at all — that passage is a Kurt Schwitters letter about museums, mistakenly relabeled as Picasso by quotation aggregators. We found no rival author and no reason to doubt the sentiment, but absent a primary source we classify it as attributed rather than verified.
