We have a small collection of original and reproductions of circus posters from $50 to $850 (for largest one at left). But none of the productions are more well know than Connecticut’s own PT Barnum. In 1871, former museum promoter and impresario PT Barnum (1810-91), in association with circus entrepreneur William Coup (1837-95), launched the P.T.
