No, but I think I may have heard of them. With chocolate and cigarettes? By the by, I recently learned that my grandfather was in Amsterdam during the Hunger Winter. He had to eat bulbs to survive. It's a very odd thought.

In my youth, there were collections for 'CARE packages' and ten dollars sent an actual food package (more than just chocolates and cigarettes) to 'the starving' overseas. As you can see from the name, it changed throughout the organization's history. I had not realized that it had largely started with the Berlin Airlift (1948), or that it even that is was an acronym with some organizational meaning.
The term 'CARE package' has been colloquialized in to American English as an idiom for a box filled with an potpurri assortment of foods and diversions provided to those 'in need'. Concerned empty-nester mothers send 'CARE packages' of goodies off to their fledgling progeny, even if they are cosseted in the basement.
