The world's largest foam party and three other things to do down the shore, June 30-July 2

 Sports Cards, Toys, Comics and Collectibles Show

Last year, a single baseball card sold for $3.12 million. The record-breaking card was valuable because it featured Honus Wagner, a Pittsburgh Pirate in the early 20th century. From 1909 to 1911, the American Tobacco Co. released the T206 series, a selection of baseball cards exclusively found in ATC cigarette packs –– but Wagner had stopped production of his cards. The reason? It is widely believed that he didn’t want kids buying tobacco. This weekend, hundreds of baseball cards from the T206 series will be available at the Wildwood Sports Cards, Toys, Comics and Collectibles Show. If rare baseball cards aren’t your thing, there will also be more than 150 vendors selling collectibles of every kind. Former wrestler King Kong Bundy will be selling autographs all weekend long. Come for the free admission, and leave with a bag of things you didn’t know you needed.

3-9 p.m. Friday, 10 a.m.-9 p.m. Saturday, and 10 a.m.-5 p.m. Sunday. Wildwoods Convention Center, 4501 Boardwalk, Wildwood. Free. 732-422-9365 www.wildwoodsnj.com.

Peter Max at Ocean Galleries

Although the Gunnar Nordstrom Gallery called Peter Max “one of the most famous of all living artists,” much of Max’s work has been commissioned for places that don’t garner much aesthetic attention. In 2000, Max’s 1960s psychedelic-style paintings were featured on the cover of 145 million Verizon phone books. In 2006, Max was the “official artist” of the U.S. Winter Olympics Team in Turin, Italy. In other years, his work was featured in the World Cup USA, the World Series, the Indy 500, and the Kentucky Derby. This weekend, Ocean Galleries in Stone Harbor will give visitors the chance to see over 100 pieces of Max’s work in celebration of the 50th anniversary of the Summer of Love.

10 a.m.-10 p.m. Friday to Wednesday, Ocean Galleries, 9618 Third Ave., Stone Harbor. Free, 609-368-7777, www.oceangalleries.com.

“La Traviata” Opera Dinner

Giuseppe Verdi’s famed opera La Traviata — meaning “The Fallen Woman” — opens at a party. Violetta, a high-end courtesan and the opera’s title character, is celebrating her recovery from an illness, when Alfredo, a bourgeois from the provinces, confesses his love for her. With the kind of dramatic flourish that seems to take place only in operas, Violetta hands Alfredo a flower and promises to give him a response once the flower has wilted. This story, of miscommunication and damaged reputations, will unfold Sunday at the Atlantic City Opera Theatre over a dinner of pasta and flowing champagne. Call to reserve your seat.

4-7 p.m. Sunday, Atlantic City Opera Theatre, 1617 N. Mississippi Ave, Venice Park. $23, 215-432-3099.​ www.atlanticcitynj.com.
