Even as it searches for a buyer, men’s magazine Maxim is still having fun. For one of its advertisers, Irish Spring, it’s created a special, six-page mini-magazine insert that is appearing in the March issue. With a freckled, red-headed, girl-next-door gracing the cover of the insert, Irish Spring will promote a multi-city tour, custom published editorial and the Zagat’s Guide to America’s top pubs.
