VICTORIES AND CONQUERORS
A
Victory is a brushed patch marble that has an opaque color patch on a transparent clear base. This patch covers about one quarter of the marble and, like many Vitro marbles, the patch is usually shaped like an oval with a small "v" or "hook" coming off one end. A Conqueror is basically the same type of marble, but on this variety the remaining three-quarters of the marble not covered by the patch contains brushed opaque white. One variation of the Conqueror is the "phantom conqueror," which has translucent white filaments inside the marble. The glass may be opalescent on this latter type. Finally, another variation of the Conqueror, which as yet has not been named but could be labeled the "veteran conqueror," has a dull patch as opposed to bright and brushed off-white as opposed to white. On these, the patch seems to often be shaped like a large "V." Victories and conquerors were distributed, as their names might imply, around the period of World War II.
