The hoity-toities, lubricated with orange blossom cocktails, tee-heed at the gag. The hosts were such pranksters! The event was at the 52-acre estate of Buffalo doyens Edith and W. Hamilton Gardner. The fete was a celebration of the impending wedding of two idle class fledglings, Courtland Van Clief, of the Newport Van Cliefs, and Eleanor Cameron, of the Waco, Tex., Camerons. They were to marry on Nov. 20, 1929, six days after the party — and four weeks after the stock market crash.
