Greg must have gotten this from another collector, probably something he needed to reaearch and the zine was out of print and hard to find so he got a xerox.
The Little Sandy Review was a folk music fanzine published by Paul Nelson and Jon Pankake in Minneapolis, Minnesota. Launched in 1959, the zine was dedicated to reviewing folk music legends such as Woody Guthrie and Pete Seeger, as well as then newcomers like Bob Dylan, The New Lost City Ramblers, and Koerner, Ray, and Glover. Thirty issues of the zine were published in total before publication ceased in 1965.
