few things are more fun to me than walking the streets and alleys of a city or town in search of ghostsigns. for those who may not be familiar, ghostsigns are ads that were painted onto brick walls and that remain in tact (to some degree) long after the companies have gone defunct. pittsburgh is home to countless ghostsigns, also known as palimpsests: below are a few that i have come upon while exploring the city that i call home.
