Milch-Schnitte is a popular snack sold in German language countries. Italian company Ferrero (of Nutella fame) has been producing the refrigerated cake sandwich since 1978.
In 1988, Milch-Schnitte featured Muppet Show Ausschneid-Bilder (cut-out images) with humorous tag lines and catch phrases on its wrappers, customizable into stickers for name cards, tags, and similar uses.
