The second one is the easiest Smurf album ... ever! It has been an incredible success in Flanders and Holland, and has been succesfully translated in German, French, and English (perhaps also other languages). You can find it everywhere, on every flea market, for 1 Euro.
The first one is nicer and not so usual, but it's not rare either. I have it, my brother has it, ... There are loads of Smurf singles and albums, in every language you can imagine, and new ones are still being made. When I come across one I don't have, I'll probably buy it (not the CD's, but the vinyl), but I'll never give more than 1 or 2 Euro, except for some very old ones (from the seventies).
Yes, that's one of the nice things of collecting Smurf LP's, they have often beautiful covers, nice and big, like the English version of the Father Abraham album, or the soundtrack to The Magic Flute. In the years to come, I'll perhaps post some of those here as well, but in the meantime, you can see some of them at sites of collectors like saussard or Dirki.
I'll start a thread over at 'uncatalogued' like I did for the comics, but then for albums. I'll start posting links to ebay-auctions, perhaps in the future I'll post pics of my own vinyl, and everyone else that has a Smurf album can post it there too of course.
