Pre-framed vintage posters can be a tricky thing to find - not only do they drive the price up (as framing will do for any type of print), but you also have to consider the quality and style of the framing. Many people prefer to frame their own posters, and if the frame that is already on the poster doesn't match the room you're putting it in, or you just plain hate it, it can be tricky to reframe the poster without damaging it.
On the other hand, a framed vintage poster can be a very nice find - you don't have to worry about framing it yourself, and in most cases it will be well kept and of good quality. If someone took the time to frame the print, then you can probably assume they cared about the quality and didn't want the poster to be ruined.
