Ernie had the signs made with a porcelain baked on finish.. NOT a paint, but actual baked on ‘glass’ porcelain. They were expensive to make, Ernie and I talked about the costs back then.. Some of these signs have turned up changing hands on Ebay or from estates.. and sometimes go for less than Ernie sold them for.
Ernie made these sign just like the original ones.. But Ernie had the forsight to add an intentional mark or ‘flaw’ on each sign to signify that it was NOT a near perfect original in porcelain. A near perfect original would likely sell for north of $1000-$2000.
