This one comes from quite a different place than the similar sign I posted here some time ago (the 'do not feed the elephant' one), but it looks like a part from a set o.O; This time it says 'do not touch the mammoth' XD It was taken in the JuraPark where you can see a nice 1:1 mammoth model. It's so fluffy that people pull its hair, hence the sign and the 'ouch' expression on the mammoth's face.
