area66 ---- Yep. Quite obvious that they are Steiner pages with images added.
angore ---- I did see eBay
listings from that seller for Slovak Republic pages, too. My concern was that it was all setup in A4 page format. If I print in 8.5" x 11", then the images shrink down. Not sure how much that affects the borders around the stamps.
I do use black mounts. I assume that the borders used by Steiner account for the mounts too? I haven't purchased anything yet. Just trying to make sure that the pages that I do buy meet basic requirements --- ie complete up to date pages, size of borders to accept mounts, etc.
