Olympian is a CWS product if I am not mistaken. I haven't seen the album, but I was very unhappy some years back when I ordered world supplement pages (1975-1980 or 1985), thinking somehow this was a good idea to supplement my Harris Album. This was when I was restarting the hobby and thought world-wide could be collected in Harris or pseudo-Harris albums. The supplements were horrible - poor coverage, poor printing, as if it had been run through a copier, very thin paper, countries laid back to back on different sides of the same page. I tossed it in the garbage.
I wouldn't buy from CWS again unless I could see the product first hand before committing. Don't purchase this album unless you are prepared to return the item. I could be wrong though as I haven't seen it.
For my taste, it was a mistake from the start. I decided to specialize rather than collect worldwide, for reasons other than availability of albums. However, if had decided to collect world wide, I would have gone with Scott International (e.g., Big Blue) albums, despite the expense, possibly looking to
ebay for acquiring used albums. Or I would have used Steiner pages, and printed as I needed them.
But, keep doing research and get other opinions.
