My father went to Europe in 1962 and visited the Vatican... I have 8mm home movies from the event, including a sighting of Pope John XXIII, not well, speaking from his window. This little document was in his travel papers, and appears to be a mailer for Papal Blessing Forms from Galleria Savelli, the church supply store. It is postmarked Rome (with a 1 Lire Marca da Bollo stamp) and carries a 1962 date.
