Help figuring out this “Live Undead” cassette

Hey there. Posted this here before but I had been drinking and posted it with the wrong album name. Not sure if I deleted it or what but….

ANYWAY! Found this copy of Live Unded at a thrift store and when I got home I looked at the J-card and it’s all hand drawn inside. Anyone seen anything like this? I’m just trying to figure out if there are others out there like this or if this is just some rad kid in the 80s personalizing his Slayer tape. Maybe that rad kid is on this forum and I can reconnect him with his childhood cassette.
