Jazz at the Pawnshop - LP

To Gdupont - what you have is the original issue "premium" version.

To Grimace - You're right - it is an excellent live recording of a slightly above average performance. More of a fun virtual reality experience than a great moment in music. That being said, there is some very good Scandinavian jazz out there.

And to Stanwal - I hope you kept one of every lp they distributed! A great catalog, whoever was behind Audiosource had a great ear. Whenever I see an LP with an Audiosource sticker on the back I buy it.

The original 1st pressing is the orange label with printing PROP 7778 on the dead wax, not handwriting.

This was one of the very first "Audiophile Recordings". Endless reissues were made, some good ones, some average ones.
But, do you know, there was made another one from this Session 1 day later?

Opalchip,
I have the original issue "premium" version. Do you have any idea what this might be worth? Or where I can find out ?

I'm assuming you're referring to the Audiosource edition similar to Gdupont's above. That one generally goes for around $40 on Ebay if mint. The monotone orange label one that Tongnam mentioned is the more expensive - going for $70 or so.
Both of them can randomly sell for much more on Ebay, though, depending on how crazy two or more bidders are feeling. I've seen them both go for over $100 - but that's happening less now with the economy fading.
