On April 19, the non-profit organization Empreinte invited for the opening of the "Print Making" exhibition in the CARRE 1, rue de l'Aciérie L-1112 Luxembourg. There are exposed works of contemporary engravings. As engraving played a key role in the first 100 years of postage stamp production, POST Philately exhibits a selection of original engraving plates. On Friday, April 27, the Belgian engraver Guillaume Broux, will be present and will give interested parties the opportunity to follow his work live.
