Jazz at the Pawnshop - LP

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?
"Good Vibes at the Pawnshop Jazz Club"
PROP 9588, red/white Label

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.

I just bought an unopened copy on ebay (solid red label, prop 7778-79 in handwriting on the cover, barcode 7392004777792).  It sounds fantastic.  The vibes and clarinet gave me chills.  This is my personal favorite jazz album but I didn't have a turntable until now.
