Connie,
Yeah, we've all speculated about that portrait. Maybe it's a painting of one of the Smith Brothers. Then again, the guy looks like either Sacco & Venzetti. (I'll bet that Raineypark's grandad, like mine, used to "comment" on that putative case of injustice.)
The guy also looks like he could the ancestor of actor Avery Schreiber (frequent Match Game Show celebrity contestant) or, possibly, the great-grandfather of former St. Louis Cardinal relief pitcher, Al "The Mad Hungarian" Hrabosky!
Bob the Bartender, who thinks that Willie Loomis would have looked cool with that same style of handlebar moustache.
