O 'Boatman explosion signature is not out of print. Because there is no card tour on the back of the card, it is an out-of-print card, and there is a card tour signed by oberman on the back of the card, so the signature of oberman's explosion is not out of print. Out-of-print series of cosmic hero Altman cards include: dark subgrade Al HR, by Lian HR, Obo Altman's heavy-light form HR, Aguruottman's V2 type UR, Otto's father (written on the front: protest wins, China cheers) UR, virtual Gomorrah LGR, dreamy Beyonce Altman's blazing courage form SR, and Siro Altman-infinite form R.
