[78-L] Vogue picture record R784

[Han Enderman]

Just checked the highest priced 78s on ebay during the last 2 weeks,
and found Vogue R-784 by Art Kassel for $4208 ( ebay # 190428378284).

Seller seemed to be unaware of its rarity (as was I) when he started the auction.
I have found images of about all Vogue picture records on ebay,
but this one appeared to be lacking (though I had found images of the artwork).
But it is listed in Curry's book about the label (since I have an image of this page) .
On the Vogue Collectors website 
http://www.voguepicturerecords.org/records.html
it is indicated as possibly the rarest issued Vogue (no ill. in the Italian book about the label)

Does someone have more info on this issue (rarity)?
