The Poster Boy Takes a Dive – How an 1890s waterpark, the power of Victorian-era advertising and one man’s unlimited dreams culminated in drama at the auction block in 2023

Ask fans of GBH’s Antiques Roadshow if they have a favorite appraiser and you’ll hear many names, including one known for his big character, creative mustache styles and bold plaid suits. Nicholas Lowry is a poster expert and master auctioneer – two qualities that were integral to the story of a larger-than-life aquatic poster bathed in muted watery green depicting splashing swimmers and onlookers lining the balcony above, that made its way to the show during a 2004 stop in Portland. Join host Adam Monahan as he dives into the incredible story of Sutro Baths, San Francisco’s 1890 engineering marvel, playground, and entertainment spot, and the poster that more than a century after its printing was offered at auction and saw a dramatic result!
