Signage you wish you could emulate

The Museum of Witchcraft in Boscastle is a fantastic place, both in terms of content and interpretation - owing much of it's humour to it's founder,  Cecil Williamson.

While researching images for signage at my current workplace, this image turned up from the Museum of Witchcraft blog here.
(It is no longer in public use, rather displayed in a corridor of their private library)

Although displaying an attitude you're unlikely to find advised in interpretation and exhibit labeling textbooks or courses, it sums up in a splendid way the conflict many of us may encounter in museums, and especially galleries staging controversial exhibitions - "If you thought it may be unsuitable for your children - WHY DID YOU BRING THEM IN HERE WITHOUT SCOPING IT OUT OR ASKING QUESTIONS FIRST?!!?"
