Yeah, I think I got mine in '72...there used to be a head shop/record store near my HS that specialized in bootlegs...and it just happened to next door to our local McDonalds. So, I guess you now know where my lunch money went!
The thing is, I used to toss the paper covers of bootlegs & hand-design my own covers right on the LP jacket; so, my "Merely A Portmenteau" is a take-off of Chris' "Kiln House" cover. I have no recollection of the original cover sheet.
I guess that has carried over to these days, too, since I get a kick out of taking jpgs I've collected and design CD inserts & labels for my home burnt CDs.
