This is the front of the QSL card from the Voyager 1 Encounter with Jupiter. The card has a fold down the middle so it reduces to a standard size QSL card. The exaggerated colors in this view of Jupiter’s Great Red Spot and cloud pattern details enhance subtle variations in both color and brightness.
This is the reverse side of the QSL card with a map of the encounter trajectory at Jupiter and the contact information.
