Too fragile to touch

In National Trust and English Heritage properties, it's usual to see quite polite notices to dissuade some activities.   Even simply suggestive rather than specific signage....so for example the bunched lavender sprigs place on antique chairs to discourage sitting down.  Then there were these "Too fragile to touch" signs.  The polite way to discourage handling, and with a clear purpose too.

Now this next "Too fragile to touch" notice seems to have been touched so much, that it might also have become too fragile to touch itself....And as if that was not itself curious, it even looks in worse condition than that to which it relates....
