"Generate an image of a historic, late 19th-century polytechnic school building, reminiscent of architectural styles from the Pasadena area in the United States, with a sign or plaque reading 'Throop Polytechnic Institute' or 'Throop Institute', set against a backdrop of lush greenery and possibly Victorian-era street lamps, reflecting its founding in 1891 and operational history until 1920, as a tribute to its founder Amos G. Throop."
