I walked into a thrift store in Portland on Saturday and found seven Libbey #8475 5.5 fl-oz. sour goblets (not the case pictured above). I bought all of them for $0.99, each! Until about 2010, I used to find those fairly commonly in thrift stores down in big, bad Los Angeles. Unlike then, I am not going to broadcast exactly where I found them here!
Libbey discontinued this wonderful sour goblet in the mid1980’s. They should certainly bring it back!
