Pink Floyd “Dark Side of the Moon” poster from a great album!
Originally released in March of 1973, the “Dark Side of the Moon” album is known of its its use of philosophical lyrics and “musique concrète”, which is found in a lot Pink Floyd’s music. The album was Pink Floyd´s most successful one, and remained in Billboard 200 for 14 years! I could be mistaken, but I believe that is still a record of any album in history. 
The album has sold 40 million copies and counting, and is up there as one of the best selling albums of all time.
Personally I am also a Pink Floyd fan, and share the opinion that this is on one of the greatest and most influential albums of all time.
You can find this Pink Floyd poster here, and you can also buy the album.
