Similarly voluminous and expensive (originally), The Adventures of Sweet Gwendoline (second edition), published in 1999, has been reduced in price to $40 (£29/€32).

These are the new prices of the standard (trade) editions of each John Willie book when purchased direct from Bélier’s website, but not including shipping from the NYC-based publisher.

US customers can obtain copies of either book for as little as $10 postage.

However, for customers outside the USA, shipping (including postal insurance) can add as much as $50 (£36/€40) more for Gwendoline and $80 (£58/€64) more for Possibilities — charges which are unfortunately beyond the publisher’s control.

Nevertheless this means the total cost of each John Willie book for UK and European customers still comes down — to $90 (£65/€73) for Gwendoline and $130 (£94/€105) for Possibilities.

A better deal on new copies is very unlikely to become available. So act now if you’re serious about having these two massive collections of pioneering fetish imagery in your library.

Each John Willie book includes exhaustively-researched texts by Bélier chief JB Rund, the world’s foremost expert on the artist.

In the case of Possibilities, copies of the limited-run Deluxe edition are also available at the original cover price of $150 (£108/€122 ) plus up to $85 (£61/€69) shipping. A Deluxe edition of the Gwendoline book was also produced, but has sold out.
