ELECTRICITY PHYSICS RADIO * AUGUSTO RIGHI * 1994 ITALY MAXIMUM CARD
Country: ITALY
Condition: AUGUSTO RIGHI * RADIO
Description: FIRST DAY OF ISSUE SPECIAL POSTMARK * A Maximum Card is a picture postcard with a matching postmarked postage stamp affixed on the view side. The ideal maximum card has concordance between elements (depiction on stamp matching the depiction on postcard - or elements of it -- with a postmark that is as closely related as possible to what is depicted on stamp and postcard). However such a perfect concordance is not always 100% achievable because at the time the maximum card was processed there were no matching postmarks available.
