Steve Ditko, the Marvel Comics artist who gave the world the woven webs and soaring red-andblue shape of Spider-Man and the other-worldly shimmer of Doctor Strange, has died. He was 90. Ditko was found dead June 29 in his Manhattan apartment, New York City police Lt. Paul Ng said Friday. No further details were available. Ditko, along with writer Stan Lee, introduced the world to Peter Parker and his alter-ego Spider-Man in 1962. A year later, Ditko introduced surge on turned-super hero Doctor Strange. The adventures of both have been turned into blockbuster films. While Lee embraced his status as a creative god among comics fans, appearing at conventions and film cameos, Ditko was a recluse who won the worship of the most hardcore comic-book fans. The son of a steel mill worker, Ditko was born in Johnstown, Pa., in 1927. He served in the Army in Europe after World War II and began working in comics in the 1950s in New York, eventually landing a job with Marvel forerunner Atlas Comics. Elvis Presley’s Rolls-Royce, the suits the Beatles wore on their first tour of America, Bruce Springsteen’s sleeveless faded denim jacket and colorful headband, and Michael Jackson’s glove are among the items of music memorabilia on display at the new Hard Rock casino in Atlantic City, N.J. There are outfits worn by Lady Gaga, Cher, Barbra Streisand, Whitney Houston and Mariah Carey, and shoes from Elton John, Buddy Holly and Gene Simmons of Kiss — if dragon-scale boots count as shoes. Guitars in all shapes, sizes and colors, including ones played by Tom Petty, Bob Dylan and Slash, are there, too. When the Hard Rock opened June 28 in what used to be the Trump Taj Mahal — the casino opened in 1990 by Donald Trump — it brought many items from what it calls the world’s largest collection of music memorabilia. Still to arrive at the casino are items including a Jimi Hendrix guitar and Frank Sinatra’s piano.
