Yep, which makes it seem like it would be the less rare variation. I guess not as many people bought the album.
I think this is the album it came with (see attachment). You can still find them online, but a lot of those seem to have been stripped of their stickers, or the stickers have already been used.
Don't quote me on any of this though. I haven't been able to find any evidence of stickers coming with the albums. I assumed the "Blue Album" at the top meant it came with the album, as I remember getting activity books as a kid that came with stickers, but "Blue Album" may refer to Series 2 in general. Watched a video of a "Red Album" opening and it didn't include any stickers, so it may just be from another print run or region. Are pictures of the backs available?
