ABSTRACT:
This invention relates to an album with a replaceable front cover and in particular to one which mainly includes a thin iron sheeting placing at the each of the shallow edge of the front cover, a suitable number of raised projection and magnetic units as the back of a transparent cover in responding position to the edge of the shallow edge thereby urging the transparent cover firmly on to the shallow edge by means of the attraction between the magnetic unit and the thin iron sheet, and the fixing power of the raised projection and the magnetic units.
