Shuster's home has been demolished and replaced by another, but the fence has oversized Superman comic book pages displayed. The nearby commercial strip has a state historic marker detailing Superman's Cleveland roots.
But there isn't an outsized Superman profile in Cleveland like the way the city celebrates its role in the history of rock 'n' roll, including the iconic Rock and Roll Hall of Fame and Museum.
Comic store owner Markus Benn thinks hometown fans want to see the Man of Steel rendered in granite.
"I don't understand why Cleveland won't own up to owning Superman," he said. "What do I suggest for a Superman statue? He should be downtown, he should have the shield or the eagle, that classic pose where he's standing up there with the eagle on his arm."
The low Superman profile in Cleveland may be because Siegel and Shuster weren't self-promoters and sold their rights to Superman so early, according to Mike Olszewski, a longtime Cleveland broadcaster and president of the nonprofit Siegel & Shuster Society.
Last year the $412 check that DC Comics wrote in 1938 to acquire Superman and other creative works by Shuster and Siegel sold for $160,000 in an online auction.
Fans hope Thursday's 75th anniversary, including lighting city hall with Superman's colors, will raise the Siegel-Shuster profile. The city is making a start with a Superman day proclaimed by the mayor and giving out birthday cake at the airport's Superman display.
The June release of Hollywood's latest Superman tale, "Man of Steel," should renew fan interest. The film offers a fresh start for the kid from Krypton, with Henry Cavill as the boy who falls to Earth and becomes its protector.
Ricca said the image of Superman arriving from a distant planet and getting raised in America mirrors the Cleveland background of his creators. The parents of Siegel and Shuster fled Europe for a new life "and they end up on this alien world, which is Cleveland," Ricca said.
