Index Card From the Secretary of State of Pope John XXIII
An Index Card from Dominic Tardini, Secretary to Pope John XXIII

This card has the image of the cross-keys and tiara. In English it says:

The Secretary of State of his Holiness regrets to communicate that the Holy Father does not find it possible to grant the numerous requests for His autograph.

This card is from the time of Saint John XXIII’s pontificate.

Father Kunst included this in his collection as a joke because he has so many papal autographs.
