With that in mind, I present to you the DARK SHADOWS VAMPIRE CLUB membership certificate. This is a high resolution reproduction of the original fanclub document from the 1960s, and should print smoothly. I say "should" because I haven't actually sent it through the printer yet, myself. I like to live dangerously.
But wait! There's more! I've also added a PNG file of the wallet-sized membership card, in case you get hassled by the man when away from home. All this for the low low price of absolutely nothing.
Print them! Sign them! Share them!
