This is a very rare board by SMA / Skip Engblom (Dog Down Z Boys / Zephyr). He made only a certain amount of these as gifts for certain people within the skateboard industry. Width – 8.5. Wheel Base – 15. Construction – 7 ply maple with wood stringer top sheet made from mahogany, maple, and died maple veneers. Bottom – SMA Christmas graphic with Skips signature laser engraved. The top of the deck with the wood stringers is where he signed the deck for us.
