Stamp holder

Guru

I recently was given my great grandmothers stamp collection full of really colorful and beautiful stamps. I'd like to put them in an album, but the only ones I've found leave them not completely covered. I seem to remember years ago that the post office had an album with plastic sheets, much like the kind you find for sports cards, that you could place your stamps in.

Can anyone give me any bearing on where to find one of these or what type of album I could put this in? I'd like to preserve them for my children.
