COCKTAIL PARTY: Wow, we're intrigued. Bold Italic presents 1939. Tog to the Bricks!, a decadent cocktail party from the 1930s, celebrating the opening of the World's Fair. The organizers promise "a raucous good time while the gin and absinthe flow, photographers roam, the piano keys are plunked." Cocktails and food by St. George Spirits, Distillery No. 209, Aidells, Cheese Plus and Pacific Puffs are all included in the cover charge. Attire is 1930s inspired, of course, and the best dressed will get gift certificates to Decades of Fashion and tickets to Long Now's Rick Prelinger Lost Landscapes screening.
