De Sceleribus et Criminibus (Of Crime and Criminals) was published in 1908 as a set of ten colour lithographs by Chevrel, a well-known Parisian erotica publishing house. Complete sets are very rare.
Some of the engravings are colour versions of engravings created earlier by van Maële for other works. They represent the best of his works in colour, and vividly demonstrate his remarkable imagination.
