Fake road signs have been popping up around Frankston, Australia, amusing some and outraging others. The signs are said to be the work of a "mystery artist." From the Frankston Leader:
The mystery Frankston signs have been carefully made to look like official road signs. Drivers have reported seeing them in Cranbourne-Frankston Rd, Langwarrin. Some think they are funny while others - and officials - aren't laughing...
Although VicRoads' media department thought the signs were "very amusing", its regional director Steve Brown was not laughing. The placement of inappropriate signs such as these was unsafe and illegal, he said. "VicRoads has arranged for them to be removed immediately and may request police to assist in identifying who was responsible."
It reminds me of the Fake Road Sign Project that artists conducted in Lyon, France back in 2004 (with the official endorsement of the Lyon city government). The Lyon Sign Project used to be online at bopano.net, but that link now appears to be dead. A few of the Lyon signs can still be seen here, here, and here.
