There is no COA as COAs did not exist and in many cases COAs are worth about as much as the paper that they are printed on. I have no doubt that the autograph is real as I obtained it first hand from the shop owner that held the in store appearance. The LPs cover was obtained before the forgers that ruin this industry crawled out of their holes.
I encourage you to check out other exemplars on the internet. I did again just prior to posting this item.
Look at similar pieces from reputable dealers and collectors to compare. PLEASE NOT THAT THERE IS NO LP JUST THE SIGNED LP COVER. The LPs cover is in excellent condition when considering that Babylon by Bus was released in 1978. I do take good care of my collectibles even the junk.
