I have done my best to take photos where they are torn or stained. The posters are traditionally folded up and with their age are creased. The good news is that when framed, the creases and tears press up well against glass, and any rough edges can be hidden by mats. Any wear picked up from years are part of the vintage charm. \u003c\/p\u003e\n\u003cp\u003eThese posters are sent as unframed.
