Walt Disney's Comics #338

In "The Evil Inventor," the scheming Emil Eagle strikes again, this time disguising himself as a vacuum cleaner salesman to sneak into Gyro Gearloose’s lab and steal his latest invention plans. When that fails, he returns in a firefighter costume, luring Gyro into a net trap before making off with a stack of blueprints. With the help of his Thinking Cap and a robotic bloodhound, Gyro sets a clever trap of his own—turning Emil’s vanity against him with a wild hair-growing formula.
