I can't find any information about this exact pressing. There don't seem to be any pressing outside 1959, but this is a weird picture sleeve variant. I haven't seen any others online with a silver border with a yellow corner for the Buena Vista logo. Granted this sleeve has a heavily frayed edge along the top, making some if it hard to read, but no splits. And on the back, for some reason, there is the word "SAMPLE" stamped back there. No mention of promo on the vinyl. And the vinyl is awesome. Very clean looking and played great.
Please see pics. I have done my best to include any examples of blemishes and markings on the vinyl.
We do our best to describe and photograph each item in detail. We try not to rely on any specific grading system, such as Goldmine, for using those simplistic grades may not capture the true essence of the item, and are also subject to interpretation by the seller or buyer. Possibly increasing expectations.
