Thanks to spookshows.com for their wonderful collection of vintage halloween memorabilia and photographs, including these patent applications for various Jack O'Lantern toy designs.
Fun to see that back in 1902 ingenious minds were already at work tinkering and inventing, and the commercialization and commodification of our culture and our holidays that would come to define our 20th Century was starting.
The candle design of Mr. A.B. Herd may have given way to a battery-operated version by R.R. Authier in the 1960's but the incandescent spirit of what started as the Celtic festival of Samhain and later became All Hallow's Eve, really can't be patented.
Happy Halloween to all.
