This from the Vatican Information Service this morning:
A communique made public yesterday afternoon (Jan. 26) explains that the stamp is dedicated to the 1500th anniversary of the shrine of Our Lady of Grace, better known as the shrine of Mentorella, located in the Italian region of Lazio.
The series of 900,000 stamps, each with a face value of 0.65 euros, will be sold for 0.85 euros, though their postal value will remain 0.65 euros.
The 0.20 euros surplus will be used to aid victims of the earthquake. According to estimates of the Governorate of Vatican City State, if almost the entire series is sold some 150,000 euros will be collected.
