Welcome to Tricorn Publications, A Revolutionary Publisher offering original written works, historical documents, and classic works of prose in electronic form. This publishing house was created to provide people with electronic versions of works in the "public domain" and for writers to get their works "out there" where people can read and enjoy them.
Appears the magazine might be in hiatus as the last issue was March 2012. It's worth checking out the archives of previous issues.
(from their site) - Established in 1976 as an "an Association to promote the teaching and enjoyment of music," Ukulele Yes! became an international network of ukulele teachers with the common goal of fostering musicianship through ukulele instruction.
