Topps (TOPP) An investor group including Topps' director Arnaud Ajdler and Crescendo Investments II wrote to Topps' board, criticizing it for actions taken at a March 13 meeting. As reported, the board blocked two directors from officially monitoring acquisition offers that might compete with a recently announced -- and controversial -- bid to buy the trading-card company for about $385 million. Topps expressed concern over whether Ajdler and investor Timothy Brog could "adequately represent the best interests of the company's stockholders" given their "publicly stated opposition" to Topps' proposed merger with Tornante Co. and Madison Dearborn Partners. The Crescendo group holds 2,547,700 shares (6.6%).
