It’s been a while since we’ve had an entry into our Postcard series, but good things come to those who wait. This dynamic piece captures a diver in midair over what the postcard calls “Stillwater Lagoon” in Manhattan Beach. While we know the Blackstone Hotel had a lagoon, and that would certainly fit given the timeline (1923 postmark), we’re not sure if that’s the one shown here. Regardless – we appreciate that this eBay seller put it up. We’ve got another cool one for you tomorrow.
