The one on the right is a Hippo Pit show. I beleive that was owned by Doc Bartok.
Doc Bartok was an old Medicine Man who sold a cure all remedy know as Bardex.
He told Me that he used to play Salisbury with his Tent Show on the West Side.
He was there about a month when all the Merchants on that side of town came and asked
when he was leaving as he spoiled all their businesses. And I remember the old Hayman's Drug Store, corner of Main and Lake in Salisbury, carried his Bardex Medicine right up in the 1960's.
And still had calls for it!
