The John L. Wright company made Lincoln Bricks and Lincoln Stones, construction sets intended for use with the Lincoln Logs sets that the son of Frank Lloyd Wright made iconic. John Wright claimed he got the idea for his Lincoln Logs from the "floating cantilever construction" techniques his father developed for Tokyo's Imperial Hotel. Lincoln Logs appeared in stores in 1918, just as Americans began to worry that urbanization and industrialization would harm the nation's character and values. At that time, the country adapted symbols of the wildreness and frontier into everyday life even as the frontier itself "closed." Invoking the name of the 16th president and the log cabin he was born in proved to be good marketing. Naming brick and stone building sets after Lincoln perhaps seemed a natural extension of the brand, but they never reached the popularity of Lincoln Logs.
