As my Korean stamp collection grew, using commercially available quadrille blank sheets (Elbe, I think) and Showgard mounts, I arranged my mint stamps chronologically, but in simple rows and columns. Cancelled stamps, as there were many missing issues in my collection, were placed in a pre-printed album (probably from D.G. Phillips) using stamp hinges.
In the 1970s I decided to create a more visually pleasing album for displaying my mint Korean stamps. The plan was to work first with the definitive stamps as they were mostly in a uniform small format; then later to tackle the more numerous and multi-format commemorative stamps. The latter never happened.
