Per Wikipedia, Arosa is a statistic town and a municipality in the Plessur Region in the canton of Graubünden in Switzerland. It is both a summer and a winter tourist resort. The puzzle is one of our most spectacular: a Picture Puzzle Mart puzzle actually made by Parker Brothers Pastime cutter #726 in the 1930's. Plywood, interlocking, color line cut with 96 figure pieces, several enhanced. Cutting is terrific but so is artwork by A. Carigret, resulting in a great puzzle which is fun to assemble.
