"In order that the Connoissoeur may fully appreciate the perfect fragrance they should be smoked either WITHIN ONE MONTH of the date of shipment from Havana or should be CAREFULLY MATURED FOR ABOUT ONE YEAR."

Printed on the Top of Rafael Gonzalez Dress Boxes (the one I just finished and stopped to read the above on was from September 1983 - but checking a box of Coronas Extra from OCT 00 - same legend is printed).
