This doesn't have many of the color variations, but still looks quite nice!
Keep in mind that the more specialised your collection becomes, the fewer people there will be who collect the same.
Album publishers will want to make a profit. Designing pages only very few people use might be a loss-making proposition.
Adding those pages to an album scares away potential buyers.
This also holds for catalogues. Not long ago, I had a mail exchange with Roy Hamilton-Bowen. He edits the Hibernian Handbook of Éire stamps. This is quite specialised. It lists paper varieties. He told me that he limited the paper varieties listed in the Handbook. The reason was he had received very negative reactions on a more comprehensive listing. I think it is a pity, but I can understand that he cannot publish a Handbook only I think is what the hobby is missing.
I have a limited range of countries I collect. I do collect at a specialised level.
I make my own pages using the Lindner 'T Blanko' system. It allows me the freedom to add what I like.
My old DAVO GB albums are sparsely filled. For Ireland, I did not even consider an album, but made my own.
Most Comprehensive Denmark Printed Album?
When only one publisher publishes a Denmark printed album, that will be it.
When a second publisher adds one perforation variety, that will be it.
Printed albums, usually, do not cater for specialist collectors. When you collect varieties and you want an album, consider using a blank system that suits your preferences and make your own album.
You, also, could add blank pages to a printed album. However, if you are like I am, you might not want to have one stamp on one page with other face-values, and the colour varieties of that one stamp on an extra page, thus showing only the 'varieties' consider starting from scratch with a blank system.
