Biroco, who would appear to be an occultist of considerable erudition, has compiled a small collection of cover art from vintage smut books of the lesbian persuasion.

The covers, which you will have to view in situ, are accompanied by learned commentary, regarding their typography and other subjects:

It appears also that in Two Way Beach Girl the sexual attractiveness of the ribcage and discernable midriff contours was coming into fashion, showing a more discerning taste for erotica that perhaps reached its pinnacle in the anorexic cabbage-fed mortuary-slab Eastern European cum-shot amateurs of the late 90s, which of course will not be of interest to the connoisseur of vintage erotica.

Well said!
