Not sure how long the signage has been up and unchanged. But I'd guess a couple of decades or more.
The figure of the guy holding the suit is a bit daggy. But it has a kind of seventies charm -- although I suspect it's not quite that old.
It's not great art, sure. But it gives the little shop a nostalgic feel and I'm glad it's still up there. Hope the owners keep it there as long as possible.
