The image of the "Lucky 7" dice roll is usually made of 5 + 2, as on the cover of the Perry Mason mystery novel "The Case of the Lucky Legs", but it sometimes comes up 4 + 3, as on this gold-plated American "Lucky 7" money clip. The "Lucky 7" dice roll is found on quite a lot of hoodoo curio packaging, including 7-day candles; the character called Lady Luck, in her Irish-Amewrican World War Two incarnation, wears dice for earrings and they always show 7.
