Another feature unusual in early superhero strips was used several times by MLJ. In Top-Notch Comics #5 (May 1940), MLJs Pep Comics character the Shield guests in the Wizard story, while The Wizard appeared in the "Keith Cornell, West Pointer" story. This cross-over gimmick was repeated in #7 by The Shield and The Wizard again (although only in a 3-panel cameo). This time the appearance was designed to set up the announcement of a new MLJ title, Shield-Wizard Comics #1, advertised in the issue.
