Is this a real GT frame?

[Jurelle]

I found this on marketplace for a good price. The seller said its a vintage GT Avalanche but when I searched by image it said that it was a vintage Talera, I would just like to know if this frame is legit or not, I'm currently waiting for the seller to send a serial no.

Serial number is your best friend on this one.

It does look like a real GT.... given the shocks it may be an Avalanche....
