Hi yes
they where my first success
I got 1 and like yours it says "official merch of brandi and jarrod" on a sticker but mine is dedicated but i think its a sec dedication
it is genuine as i think its pre signed.
I also got a typed letter from them which thanked me for my support
Congrats... I wish jarrod would stop dressing like a 15 year old skateboarder though haha I got bored with that show fast but congrats on getting a autograph.
