I had another thought to attract more cost conscious worldwide collectors where the stamps may not be worth more than the album.
My proposal is to re-issue the Minkus pages on letter size paper with Scott numbers and add left side information like Mystic. The ideal case is a PDF or other image option but I doubt they would do that because people would share and copy. They would end on
ebay just like Steiner. This approach preserves International brand.
I like and use Steiner but end up with a lot of wasted space on pages. The key getting cost down is getting more stamps per page.
As many want, airmails and semi postals are not separate.
I have a Minkus Philippines album. It has a country title page, introduction page, and page index for eras (Spanish, US admin, etc).
Mystic would likely do this more than Scott or Amos Media. I get the feeling they are not into expanding but just harvesting what they have at a minimum ongoing cost (much on demand or back order). Mystic used the razor analogy by selling the razor cheap and make money from high priced stamps and supplies (all with excellent customer service).
The space insider fits on letter size page (see mockup below showing actual Minkus with adequate printable margins. Of course, anyone with AlbumEasy could do it from scratch.
Beauty is in the eye of the beholder but I find some odd charm in their pages - practical and retro. And for GeoffHa, the old font is used rather than Helvetica font.
