What is the quality of your picture mounts? They are acid free, even the core, and they are of museum archival quality and easy to mount in the frames.
How do I choose the right size? We have made it very simple, almost all our posters have a white surface around the picture which is perfectly matched in size to the picture mount. If you choose a 50x70 cm (20x28 in) poster for example, just pick a picture mount of the same size, 50x70 cm (20x28 in), and it will fit precisely without covering too much of the motif. Exceptions are if you choose a poster with full bleed (if the motif does not have any white border around it at all), or if you choose one of the very few motifs with a different cropping. For those posters it says in the product info that we do not recommend a picture mount for that particular poster, so please check that info twice if you´re uncertain.
