No stories in this issue are interrupted by ads. All advertising pages fall between complete stories.
First post-Go-Go Checks issue.
A DC house ad for this issue, appearing in Jimmy Olsen (DC, 1954 series) #103 (July 1967), reproduces the cover illustration for Jimmy Olsen #104 showing the issue as having Go-Go Checks, but the actual comic does not. Perhaps this ad was assembled before the decision to discontinue the Go-Go Checks was made or finalized.
