I can imagine the Showmen's League is no longer a large group (they were basically a trade union for the "outdoor amusement industry" (circus, carnival and amusement park) workers, so I guess they had to sell their headquarters building, but because it's decorated with their logo elephant, it's a one of a kind gem that will never be seen again.
Also a sad loss, Harry's Hot Dogs, which was in the building (you can see the awnings in the top picture above). The shop made it 100 years, and closed when the building was slated to be destroyed.
A local cemetery has a memorial to circus people killed in a train accident, called "Showmen's Rest" - I'll blog about that at some point, I'm sure.
