The Music Trade Review of 3 October 1925 ran an advertisement for three new ukuleles from the Progressive Musical Instrument Corp. — they were … (and I’m only reporting what they said in 1925) … “the Al Jolson ‘Big Black Boy’ ukulele, the Eddie Cantor ‘Golden Tone’ ukulele, and the ‘Ukulele Ike’ Cliff Edwards ‘Own’ ukulele.”
The first of these instruments was the Edwards ukulele made in two models and dealers acclaimed it the greatest hit in ukulele history. Each bears Cliff’s autographed trade-mark. They achieved immediate popularity. Following these numbers with the other two models bearing the endorsement of two of the world’s greatest musical comedy stars, names known to all theatre goers and phonograph record buyers. Progressive dealers are now recognizing these instruments as a wonderful business-getting combination.
I’ve never heard anyone anywhere (except in the MTR) refer to these instruments. A quick google has revealed nothing … except this so far.
