Magnum Editions Poster: Members of the Seattle Tubing Society, 1953

One of the rites of spring in Seattle society during the 1950s was the Seattle Tubing Society Springtime Float. The club’s members would dress in flamboyant costumes, line the banks of the Sammamish Slough with their inner tubes in hand, and then march into the river to float down to Lake Washington. They were accompanied by a bar tube that was always well-supplied.

Burt Glinn became an associate member of Magnum in 1951, along with Eve Arnold and Dennis Stock, before becoming a full member in 1954. He served as Magnum’s president twice.
