Grand Master Dale Myrberg had a number of signature yo-yos made for him by Hummingbird. This is one of the more unusual, the Dale Myrberg Trickster Concave. The same laminates available to Hummingbird were used, and Dale's custom logo was placed on one side, and the Genuine Hummingbird logo on the reverse. Beautiful Yo-Yos, and several color variations.
Of most interest is the concave configuration. Hummingbird made Tricksters for years, but never a Trickster Concave. Only a few special orders were for Tricksters in the concave shape.
Pictured here is a Dale Myrberg Trickster Concave in Purple, Teal, and Pink Laminated wood. Also, the Myrberg logo is on both sides of this yo-yo. No "Genuine" logo on the reverse.
