Blue Cavern

I won this album, but I don't know where the stickers are supposed to come from or how many of them there are.
It's from Germany, so does anyone know anything about this?

I like that...maybe Tojo or Dominique has seen these in the shops

Hi Paolo,

is this a new product?

I haven't seen one of these but I can look out to see whether our kiosk in the village has something like it & the stickers to go with it.

I don't think it is new.
I have contacted the seller to have more information about it.
