Hi guys
Looking for some friendly and expert opinions on this stallone auto.
Now I received this as part of a rewards scheme offered here in the uk from a very well know and respected music and film store called HMV.
They offered many cool signed pieces a few years back and I was lucky t get this stallone letter and came proffesionally framed.

I believe this to be original.
I was looking to sell but it's authenticy was questioned in a fb group and mid was very rude about it.

Any help would be greatly appreciated

Thanks
