Chris Ferry Sr. received a text message at 8 a.m. Wednesday from someone who was not in his contacts wishing him a happy birthday.

Ferry, who turns 62 on March 16, called the guy back and said, “Who are you? Where did you get my number? How did you know it was my birthday?”

The man on the other end of the phone said, “I saw it on a billboard.”

Ferry, of Linwood, the president of Chris Ferry Insurance, has received hundreds of phone calls and texts wishing him happy birthday since Wednesday, thanks to a billboard on the Black Horse Pike in Atlantic City.

A billboard that says, “Wish My Dad Happy Birthday — Love, Your Sons, 1 (561) 307-4879,” greets drivers on the right-hand side of the pike before the intersection with West End Avenue. A picture of Ferry’s face takes up the left side of the billboard.

Ferry knew it was his sons as soon as he heard there was a billboard, but he had to see it for himself.

“I’m totally flattered. I’m enjoying the attention. It’s all cool,” said Ferry, who added he has unlimited talk, data and text on his cellphone plan. “My phone is blowing up.”

Ferry’s oldest son, Christopher Ferry Jr., 30, of Boynton Beach, Florida, came up with the idea.

“Not only is there the billboard, we put it on social media as well, Facebook, LinkedIn and Instagram. He is getting calls from all over the country, South Carolina, Alaska, New Hampshire, New Jersey. He got a couple of calls he said from Luxembourg, a different country,” said Ferry Jr., who owns and operates the Boca Recovery Center in Florida and is heavily involved in marketing and social media.
