Why is Ukulelia the World's Greatest Weblog? This kinda stuff.
In poking around this morning I found a few interesting items in Google Book Search. First, meet Morris Rothman of Bayonne, NJ, who patented this neato combination walking cane and ukulele. Anyone ever played one?
Next up, sneak a peek at Miss Una Fleming of Los Angeles, CA and her 5-foot ukelele (sic). Also on this and adjacent pages, check out the "Singing Cocoanuts," "Banjochestrion" (a combo banjo, piano, guitar, harp, and mandolin), and "Luminaphone" (an instrument that produces music by beams of light, invented by Harry Grindell Matthews, inventor of the Death Ray!). Scroll up a page and "Look Out, Boys, for the Electric Spanker!
Also, wanna make a nifty cigar box uke? Have at it! (h/t to King David Ukulele Station)
On the serious side, here's an article from the December, 1919 issue of The Wood-Worker spotlighting the ukulele factory of Frank Bremmerman of Indianapolis, IN. 120 ukuleles a day! (Here's a video of latter day Hoosier Geoff Davis playing one of Mr. Bremmerman's ukes.)
