Woodstock Movie Poster - Full Sheet

I have had these posters for over twenty two years. After much searching, I have been unable to find another example of it. If you know how many variations of the Woodstock poster that are out there, you will appreciate the depth of that statement. The one that you see in the picture is in a little rough shape but the second one is still in the plastic wrapper with the price tag of a one dollar on it. Because it was rolled and priced, I assume that the poster is a "head shop" product and not a publicity piece. I spoke to the Woodstock museum about it and the director told me that he had only seen it one other time, in a private collection.

The posters have the copy write mark of Warner Brothers on the bottom and the date of 1969. If someone could give me some information about this poster I can determine whether to keep it rolled up or have it mounted for display.

Thanks in advance for your help.
