About the series
Casper the Ghost, published by St. John from 1949 to 1951, introduced the friendly specter in a five-issue comic series that predated his famous Harvey Comics tenure. Written primarily by Isidore Klein, these early stories established Casper’s gentle, non-scary personality and his desire to make friends rather than frighten. The series is notable for launching one of the most enduring all-ages characters in comics, setting the foundation for the beloved icon’s decades-long popularity.
