For a guy who turned 100 this year, Mr. Peanut is looking pretty good.

Sure, he comes across lately as being a little too hip — what’s the word the kids use these days? — for his age, sort of like that creepy old uncle who pretends he’s into your music and wears his shirts a size too small. But like that uncle, he’s a beloved member of the family, and everyone has just learned to smile and nod when he launches into a joke that’s just slightly more off-color than might be appropriate for the family reunion.

Mr. Peanut has been made over more times than that neighbor who hosts all the cosmetics parties, but he’s still Mr. Peanut, and Suffolk loves him.

This year is the 100th birthday of the Planters Peanuts spokesnut. He was born in Suffolk’s Hall Place neighborhood in 1916 when Suffolk teenager Antonio Gentile drew him for Amedeo Obici, the founder of Planters Peanuts. Legend — repeat with us, “LEGEND” — says Gentile drew him in response to a contest to come up with an advertising icon for the company and received a $5 cash prize.

A century later, Gentile’s legacy will finally be recognized in Suffolk with a historical marker near the spot where his family lived. The marker will be unveiled at 8:30 a.m. at the Hall Place Park in the 100 block of Hall Avenue.

It’s a fitting tribute to the famous legged-legume, and it’s one that the Hall Place Civic League started trying to put together way back in 2007. To see the efforts come to fruition, finally, through the efforts of members of the Peanut Pals organization is a wonderful thing for those who recognized nearly 10 years ago that there was something to celebrate about the young boy whose sketch would become a legend of snack food marketing.

To have the efforts pan out during the 100^th anniversary celebration is icing on the cake — or nuts on the sundae, if you prefer.

Saturday’s celebratory events also coincide with Peanut Fest, an event where Mr. Peanut has always been right at home. There will, as in years past, be a big parade downtown at 10 a.m., there will be a Peanut Pals swap meet at the Suffolk Center for Cultural Arts — bring your stuffed Mr. Peanut toy for an appraisal — and there will be a Peanut Fest 5K and 1-mile walk at 7:30 a.m. at Constant’s Wharf. No word on whether peanuts will be distributed to the participants, but we know a place or two downtown where they can be found, either way.

So, grab your monocle, spats and cane — or just throw on a pair of shorts and a T-shirt — and join the party.
