That isn't how it works. Just say for example that the Hulk appeared in another comic that month like Marvel Team-Up. In that case, your use of apn could be incorrect as the Hulk may have appeared in that comic before the previous issue of Incredible Hulk. In other words, whenever you use 'apn' instead 'a' for appearances you MUST be working off of a chronological source such as the Marvel Indexes or Marvel Chronology Project.
