I have a album which says; Jimi Hendrix "Smashing Amps"

I don't know how much this will help, but here's what I can tell you. The vinyl in question is a bootleg (unofficial release). From what I understand, it's a rare find. It was released on different couleurs of vinyl and the covers could vary as well. I did a quick Google chercher and saw prices ranging from $50 to almost $120. I don't know if one color of vinyl is worth plus than another, but I suspect that all comes down to the condition of the disc and sleeve - ou how badly someone wants it.
