The earliest signature of Altman Card is the legendary UR Card. The front of the card is engraved with gold Otto, and the numerical code in the lower right corner is SER. From the legendary first bomb to the legendary eighth bomb, there are 28 UR signature cards, which are now out of print. Since the collection of the legendary ninth bomb, the number in the lower right corner of UR signature card has been changed to the familiar USR. The front of Altman card is still only Otto's signature, and the front of monster card is Chinese. Now it is out of print and has a high collection value.
