This is a letter Euronymous (Øystein Aarseth) typed and signed, and sent to Svein Egil Hatlevik from Fluerety (who I sometimes drum with, hence me recieving this gem). The letter roughly reads:
"here's your Burzum and Mayhem records, I'm working on releasing the Emperor/Enslaved split, Helvete shop has closed down for now."
The signature is written in pen, in English it translates as "war and sodomy", and has what looks like a communist star, amongst other fanciful decorations. Sorry about the picture quality but it is framed and I was hesitant to remove it. The letter is from 1993.
A close up of the signature also below, if anyone has any indication as to what the scrawlings are, please feel free to let me know.
