It simply means that NOTHING is to be posted .
';Bill'; means handbill and it is a poster or advertisement, usually dealing with movies or theater shows, but could be anything, even bumper stickers. In New York City the problem was such that poles supporting traffic lights and street lamps would be completely covered with various small notices and scraps of paper. With time these things tend to become partly unstuck and the light pole looks like a vertical trash heap. Last year I noticed that these poles had been resurfaced to a height of about 8 feet in a black, bumpy stucco-like paint that has a slighly slippery surface to which it is absolutely impossible to adhere any sort of sticky paper, and it seems to work very well. The ';post no bills'; stencilling on the temporary plywood enclosures erected around construction sites are usually cover in short order with movie posters. ';Post no bills'; translates to ';Paste your poster here';.
it means ';don't put any flyers or posters on this wall';
It means that no one can put up an advertisement there.
