'''''Booster 1''''' was a vending-machine set released on March 1, [[1999]], as one of the very first sets in the ''[[Yu-Gi-Oh! Official Card Game]]''—preceded only by ''[[Vol.1]]''(released the month prior). Like all [[Series 1]] sets, ''Booster 1'' cards used the [[Card layout#Series 1 layout|Series 1 card layout]], distinguished from later layouts by the lack of a [[Card Number]] beneath the card's artwork and the [[Eye of Anubis Hologram]] in its lower-right corner. Like the other ''[[Booster (series)|Booster]]'' sets, ''Booster 1'' was distributed via [[Carddass]] vending machines.
