. I am listing the last of the skateboard items I got. There is a slight chance I might get more, but I am not counting on it. Vintage 1980s skateboarding Alva Dolphin Tail. There are no Alva manufacturing marks on the piece. The only way I know that this is an Alva piece is the price tag. It states that it is an "Alva Dolphin Tail $5.50 marked down to .91". NOS. New Old Stock. Good condition.  You get the price tags for free. Take a look at the pictures, Ask questions first, You get what you see. Thanks, John  I do combine shipping.
