Grateful Dead Live At Radio City Music Hall Poster-(see Details)

27 1/4" high by 21 1/2" wide. Originally picked this poster up in the mid 1980's. And have had it ever since wrapped in a tube. There is yellowing on back Of poster, and the bottom right corner has some slight tearing, as can be seen in my pic. I have not had it authenticated, but have done some research on duplicates, etc, and believe this is an original.

Being I've had it since the mid 1980's, I doubt it's a pirated poster. But my question has always been if it was a first print poster, or an after print. As I said, I'm not 100% sure, and I'm not an expert in any way, shape or form with concert posters.

I'm sure anyone versed in this kind of work, can tell from my pics of the posters authenticity. There are 4 very small tack holes in the far four corners of poster, and some slight tearing on upper left side of poster, apparently from where it was hung for advertisement. Please view pics to get a more accurate idea of item's condition.
