VERY Rare. This is the original 1971 Hallmark 1st Belgian Edition. Beautiful book with pop out features. Rare Tintin items like this are gaining in value right now due to scarcity and age. 

CONDITION: Excellent condition considering age and rarity. All the Pop up features are working and present, some have minor creasing/wear. Spine is very good and solid with some minor wear. The cover is very nice minor wear only, edges/corners have some rubbing. Pages are very nice with some yellowing and a few faint blotches in places. No drawings or inscriptions throughout. Please see pictures.
