It’s shaping up to be a good day to be a Boston ad agency. Allen & Gerritsen said Tuesday that it has been named the agency of record for Friendly’s Ice Cream LLC, the Wilbraham-based restaurant chain. And Mullen, meanwhile, said its North Carolina office will be the lead agency for the Pep Boys --- Manny, Moe, and Jack; an automotive aftermarket chain.

Neither agency disclosed billings for its new account.
