Story continues on inside back cover in black and white and concludes on back cover in color. Oddity: the foreign trappers and traders are obviously Russians, but are never referred to as such, being called "strangers" and "foreigners," instead. It appears that the references to Russians were changed after the issue was lettered. However, names such as "Vasilenko" and "Radov" were not changed.
