DENVER, Pa. – Morphy Auctions’ gallery was a hive of activity prior to the company’s May 11-15 marathon auction series that grossed $5.4 million. The attraction was a 3,400-lot array of rare antique and vintage items that ran the gamut of American amusements, from 19th-century railroad memorabilia and coin-op machines to mid-20th-century petroliana and automotive signs.
