Here the continuation of the retrospective which we have offered to our faithful readers on graphic creations of ESPACE LOLLINI in the world of philately.

For this Sheetlet, we chose an unusual framework, the exploration of the stars "X" which is a still unknown subject of the postal administrations, it is true that the Chandra telescope, and especially, the giant satellite XMM "NEWTON" of ESA put this astronomical discipline under the projectors ofthe actuality.

6 satellites are illustrated, certain very old there like European Exosat, and Japanese Uhuru - this series of the " invisibles" stamps was possible thanks to the 4000 drawings of satellites which we constituted in these latest years. These same subjects will be used soon in our Space Encyclopedia.
