If they are your favorites make two copies. Frame one and put it on the wall. Nothing I hate more than hearing about a favorite picture in storage so it won't get damaged. What's the point having it if it is never going to be seen.
The second one put in an archival sleeve and, in my case, throw it in a a tough as hell portfolio box. The second is to replace the framed one when it gets nailed by one of the three year old tornado's missles. I do not mount the second set. For color and BW The framed one is corner mounted on archival board and as sealed as I can get it in the back.
