sentences:  Posted to Mauritius in 1876, Evans assembled an extraordinary collection of that country's stamps.These included a famous example of the One Penny Red "Post Office" Mauritius lightly postmarked on an envelope, which may have contained an invitation to the governor's ball, and several unused Two Pence "Post Paid" in indigo and dark blue.He sent a paper on these issues to the "Congrès International des Timbrophiles" at Paris in 1878, which earned an award from the Société Française de Timbrologie.
