LONDON.- The Evening and Day Sales of Modern and Post-War British Art concluded today with a combined total of £8.5/$13.5 million. The top lot of the Evening Sale was L.S. Lowrys Railway Platform of 1953 which sold for £1.1/$1.8 million (est. £1-1.5 million, further details on the painting below). A highlight of the Day Sale was a cast of Lawrence Holofceners iconic bench The Allies – the life-size cast (number 3 of the edition of 7) of the landmark on Bond Street which depicts Churchill seated on a bench with Roosevelt. A heated bidding battle between bidders both in the saleroom and on the telephone ensued, resulting in the work finally fetching £253,250 almost four times pre-sale expectations (est. £50,000-£70,000) setting a new record at auction for Holofcener. The sale of the first painting by abstract expressionist post-war artist Nat Tate ever to appear at auction, Bridge no.114, sold for the above-estimate sum of £7,250 (est. £3,500-£5,000). One
