I have a set of the glassware you refer to. I purchased my glassware in Nairobi, Kenya in June/August of 1979. The glassware comes in Clear & Ruby with various Big Game animals etched into the glass. Hence "Big Game Collection".
They were purchased from Rowland Ward LTD., (East Africa), City House, Nairobi, Kenya. They were made in Western Germany (Bavaria). I had them shipped to the U.S.
I have quite a collection from tumblers, water goblets, decanter, tankard, wines, punch bowl, & water jug, some in clear & some in ruby. All are in mint condition. The street value is approx. $4000.00.
They might be for sale as one unit.
