heheee... this brings up memories since my childhood, during the communist era, but in a time when things were not that bad, up to the very early 80s. I had an uncle who was a waiter in a famous hotel and when we went there he would provide us a case of Pepsi bottles (the plastic cases with dividers for each bottles - I have no idea if those have a name in English). And it was that logo on the bottles. And me and my sibling would share one bottle per day, so it would last longer.
