Mullen edged Fitzgerald + Co. to win American Classic Voyages' estimated $5-8 million Delta Queen marketing account.
The Miami-based cruise line win, coupled with the Wenham, Mass.-based shop's triumph in the$7-10 million Stop & Shop review last week, signaled the end of Mullen's yearlong new-business slump.
The shop's Pittsburgh satellite bested Fitzgerald of Atlanta for the client's Delta Queen river cruises.
Peter A. Mayer Advertising in New Orleans was the incumbent.
Mullen recently added the Pittsburgh outpost when it absorbed Bozell Kamstra's office there as part of a broad restructuring by IPG.
Separately, Mullen, which operates a third office—Mullen/LHC in Winston-Salem, N.C.—now replaces Boston's Arnold on Stop & Shop's broadcast assignment.
Arnold did not participate in the review in which Mullen topped Cronin & Co., Glastonbury, Conn., and Merkley Newman Harty & Partners, New York.
Pile and Co. of Boston oversaw the process.
"Stop & Shop is a great brand that has tremendous growth opportunities ahead of them," said Joe Grimaldi, chief executive officer of Mullen.
The victories are Mullen's most notable client gains in a year that saw it come up short in competitions for Lockheed-Martin, Olympus and Beth Israel Deaconess Hospital.
Mullen and J. Walter Thompson in Atlanta are among the contenders for the $15-20 million U.S. Department of Defense's Joint Recruiting Advertising Program.
