A giant papier-mâché bowl I found in the trash. Since I'm getting rid of stuff, I didn't bring it home, & didn't have the urge, even though I liked it & could see all sorts of uses for it, even with the broken rim.
For years I filled my apartment with found furniture, dishes, books, & even clothing, for example some fine-wool undershirts I found on lower Fifth Ave & always claimed were Patti Smith's. People throw out amazing things. You can easily find out when the rich people put out their trash but even without trying, there's terrific finds everywhere.
Interestingly, the only Schooner Island I can find in Massachusetts is a nature preserve in Rhode Island.
