I recently purchased the subject version of The Incredible Kai Winding Trombones as it was the only unused version extant. Apart from being "taller" than a jewelcase or digi-pack, I must say that the packaging is superb. It really does resemble the original Impulse! LP jacket down to the smallest detail, including glossy slicks pasted on thick grey cardboard, and the CD label is closer in appearance to the record label than the last round of domestic Impulse! digi-pack releases. The CD itself is stored in a very soft, gauze-like slipcover. From what I could decipher on the OBI strip, the K2 process was used for remastering.
