The 10-foot tall billboard, which stands on the 405 highway near Culver City in California, has led several motorists to stop and take pictures, posting images of the appliance across microblogging sites.
The controversial billboard with 'Hitler kettle' ad
"That Hitler looks like a kettle," commented one user of Reddit.
"He even has his right arm extended," wrote another, while a third added: "I'm a little Nazi, short and stout."
Kettle as advertised on JC Penney website
According to the British Daily Mail newspaper, another motorist tweeted: "Every time I see that JC Penney billboard with the teapot, I keep seeing Hitler. Seriously, the thing looks exactly like Hitler."
Proving the billboard may not be the best advertising for the retailer, another commuter tweeted: "Uh, no thanks, JC Penney. I don't think I want your HITLER teapot."
Other social media users added that they dreaded to think what the store's pressure cookers must look like.
The kettle - officially the Michael Graves Design Bells and Whistles Stainless Steel Tea Kettle - retails for $50 on the JC Penney website.
This stainless steel tea kettle has all the bells and whistles you'll need - a cool-touch handle, space-saving design and a delightful whistle to let you know when it's ready to pour," the website stated.
