The post does not have much to do with technology this time, but I’ve noticed this tin can because of the age and the designer graphics from times gone by. That’s why a few pictures of it must come in here. You do not see that very often anymore.
As can be seen in the photo, the instant powder can is the packaging of Ovomaltine.
Ovaltine contains the ingredients barley malt, milk powder, low-fat / de-oiled cocoa, whey powder, glucose syrup, yeast and honey. From the names of the ingredients is also the name Ovomaltine together: ovum (Latin egg) and malt (English malt). The high proportion of malt gives the Ovaltine their typical taste. Like the powder of instant cocoa drinks, Ovaltine is ready to drink after being stirred into cold or warm milk. (Wikipedia)
