Currently, we do ship posters and frames together but unmounted. Below are some instructions to mount a poster into the frame.
Steps to remove the back of a picture frame:
Remove the packaging from the frame and locate the small metal tabs on the back of the frame
Bend the tabs through 90º
Once all the tabs have been lifted out of the way, the rear of the frame can be removed and the picture inserted into the frame. Replace the back of the frame and bend the tabs back down to hold the frame in position
If the poster is not fitting into the frame, please read here: What should I do if my poster doesn't fit into the frame?
