It is a pretty interesting place and while walking around seeing these relics of the past, I was reminded of our classes on Typography. Besides the signs, some of which will never be seen outside of a museum, the sign painter's tools are also on display. Who can remember this sign.
The Kelly Springfield sign is faced with sheet metal. The “lights” are simply holes that have been punched in the metal with the hole metal bent into the back side of the sheet metal. This picked up the light and produces the appearance seen here. These kind of sign were used between 1900 and 1920.
The next three are just some of the colorful signs. Some icons that are seldom seen today.
The fourth photograph (from the left) you might recognize from the banner image on this page. The banner is a composite or panorama of this photo and another. Not photographed with intention of merging together, the perspective is not true. This last one the the Frisch's “Big Boy™” that you may have in your neighborhood.
