It can takes years, in fact it usually is for me a 10 year period before I get the first sight of it. Street Survivors took a good 30 years because I used a heavy outer sleeve - the paper inner and cardboard cover protected the album for a while. Not like a picture disc which is against the pvc directly. Another 1978 LP has a poster as it’s cover, and was dropped into this same type of PVC and it was fine for decades until 5 years ago started a tiny bit of fog to appear. I got it out, and saved but forgot to consider Street Survivors. SS I wanted to protect because I thought in 1977 or ‘78 that it was going to be rare (flame cover). God the original issues of this LP are beautiful, more beautiful that they are rare covers. Or did the flame cover finally appreciate in value? For me it’s 8 to ten years minimum to see it happen. But I guess hot rooms could accelerate it. The respondent should not have to wait years for the study to begin is all I’m saying.
