For an anecdote concerning the Moens catalogues and the Director of Posts in Finland, A. Gripenberg, we give an excerpt from L. Hanciau, The Postal Issues of Finland, Stanley Gibbons Monthly Journal, June 1904, vol. 14, p. 266-267.  Hanciau was the brother-in-law of J.-B. Moens, and long-time editor of le Timbre-poste and the catalogues.
