I found this one in Southern Maine and doubt it has travelled very far. Both the SLOW and the the STOP were hand-painted; the former carefully stenciled and the latter obviously not--as if stopping were an afterthought, or the red painted octagon didn't adequately communicate stop on its own!  I am partial to the SLOW side myself, believing it a useful instruction and reminder applicable to most everything, but it occurred to me the STOP sign might be a handy one too, particularly for carrying at protests. I really love how worn and weathered it is too, surely having been used to shepherd many a child to safe passage.

 20" t x 13 7/8" w x 1". Much weather and worn as evident. The handle, held by three screws, has a bit of side to side wiggle too--I haven't tried, but will, to tighten it up..
