A boom-era time capsule from the sun-drenched streets of 1920s Miami, this 1927 Vupack Mailing Card novelty packet crackles with the energy of Florida's great land rush — inside its ornate floral cover, hand-inscribed simply with the year the buyer tucked it away, fifteen miniature black-and-white views spill out depicting the Royal Palm Hotel standing grand against Biscayne Bay, the Million Dollar Causeway thick with crowds, an aerial sweep of the waterfront, dancing guests in midwinter sunshine at the Flamingo Hotel, Royal Palms at Coconut Grove, a swimming pool, and most evocatively a posed group portrait captioned Seminole Camp, Miami, Fla. — Seminole women and children in their distinctive patchwork regalia flanking a man holding a rifle, a commodified yet irreplaceable documentary glimpse of the Seminole people during the tourist-exhibition era. The outer cover, copyright UCB 1926, doubles as a Vupack Mailing Card (2¢ printed paper rate) and bears the handwritten notation "1927" on the reverse; a second inventory pencil notation reads No. 391.
