The Jewish Museum, New York takes a nice approach to rules in their gallery. Rather than explicitly forbidding things, they use some friendly humour to emphasise what visitors can do.
We know visiting museums can really work up an appetite, but eating and drinking in the galleries just isn’t kosher. Fortunately, our cafe is!
Visit Lox on B level when hunger strikes you.
The artists in our exhibitions use every kind of media—ink, paint, charcoal, gouache, etc. If you’re feeling inspired while you’re here, please write or sketch in pencil!
Museums don’t need to be intimidating or stick-in-the-mud. Another nice example I’ve seen was at The National Trust’s Speke Hall property in Liverpool. Instead of having signs on the furniture saying “Do not sit” or roping things off, they had a small bunch of holly to discourage visitors from plonking themselves down on objects meant only for decoration.
