Irresistible by the dozen! As many as 12 "fat ladies and other angels" cavort on the pages of the perpetual birthday calendar and will accompany you for years. Printed digitally on 280 g/m² chromosulphate cardboard, which is also easy to write on. If desired, the pages can be finished with a high-gloss layer for an additional charge. However, this might limit the writeability with permanent markers for smooth surfaces.
