This was my daughter's when she was in high school.  She was a huge Blink-182 fan.  It has surface wear and rough edges from use.  It could be straightened and even framed.  

This is not a poster. This is a school pocket folder which has been used and does have some torn areas on it. It opens like a book with the inside of each side that is a pocket to hold school papers. The photos are of the front cover, the open middle and the back cover..
