Sold in their own right this one actually came from Weetabix and was presumably obtained by saving up enough vouchers and sending away. The set of cards were also given away with Weetabix and have similar topics to the more well known brooke bond tea (Cars, Animals etc). Vistascreens were also popular tourist souveners with packs being available from most UK tourist destinations. I picked up the weetabix viewer at a collectors sale and one of the original vistascreens at a collectors market in Dublin along with views from Brighton!
