Lovely not-warning signs

Love these encouragement signs that create delight by subverting expectations.

They work in two simultaneous and complimentary ways:

  1. Our expectation that at National Trust properties lots of things are probably restricted and that we should conduct ourselves in a reserved English manner.
  2. Clever visual design that makes them seem like they're about to prohibit something expected (photography, playing, use of mobile phones) where in fact on second look, they're encouraging it. 

The full set can be seen in situ here, and presented by the agency that created them here: The Click Design Consultants (warning, contains horizontal scrolling).
