It seems that back in the days, like cigarets in the US, you had collectible cards with your chocolates in Belgium. The former chocolate factory Victoria used this technic to attract customers, and it worked for a time.
This album seems to be complete, and relates the story of Les 3 Mousquetaires by Alexandre Dumas. Super vintage, and super desirable.
Like every item on The Curious Picker, this item is cleaned manually.
