In March 1862, with
Louis Hanciau, Moens published a catalog of stamps, the
Manuel des collectionneurs de timbres-poste (Handbook for Stamp Collectors). This work is the first of its kind in Belgium and the second in the French language, following that of the Parisian,
Alfred Potiquet. Also in 1862, he published
De la falsification des timbres-poste (On the falsification of postage stamps) to alert stamp enthusiasts to the abundance of
forgeries. He began the first French language philatelic monthly,
Le Timbre-Poste, which ran from 1863 until 1900, as well as a series on
fiscal stamps from 1874 until 1896. == The Mauritius "Post Office" stamps ==
