The 1st printing poster is extremely similar to the reprint. When looking at the back side of the poster, small vertical rows in the paper stock are visible which are not in the reprint. It measures 14" x 20".
The 2nd printing looks very similar to the original. However, this printing does not contain the vertical rows in the paper stock. This printing was printed and shipped directly to a record company for distribution to record stores around the country. The 2nd printing, which do not contain rows, are very difficult to find and are in fact more rare than the 1st printings. It also measures 14" x 20".
