"Anonymous Engravings on Ecstasy Pills" is an interesting picture book by artist Frederic Post. This unique novel features illustrations of ecstasy pill engravings found by the author.
In the book, Frederic Post has redrawn the over 500 signs on the ecstasy pills he has found in a larger view. He also includes 1:1 scale embedded pages that mimic actual ecstasy pills. This book surely isn't for everybody, although many might find this drug art rather interesting.
