Seems like they are "going from the tapes" but I wonder if the tapes are even with the originating labels? Caprice has the Eje Thelin stuff as far as I know, maybe they licensed the old Metronome session? Don't know who handles Vogue at this point. Zodiac is another one I'm still searching for - have had bad luck with poor condition OGs. Really nice record.
Ah I see that Sony owns a lot of the French Vogue masters. I'd highly doubt they care enough to license this Wilen title, so it's probably a bootleg. "From the tapes," when it comes to these hyper-rare items, often makes me think that some collector has second-generation copies of the masters, or bought the masters off someone, rather than there being any "rights" assumed.
