The pristine copy of Superman No 1, the character’s first solo title from 1939, was discovered in an attic in California last year
A copy of Superman No 1 that was discovered in an attic in California last year has become the world’s most expensive comic book after selling for US$9.12m (£6.96m, A$14.14m).
Superman No 1 was published in 1939 and was the Man of Steel’s first solo title. It marked the first time a character that debuted in a comic book had their own title devoted entirely to them.
