These 7 plates are a must-have for any retro lover.
They are made from very hard vintage melamine plastic, which is hard to get hold of now a days (unlike the more common English Melamine). Because of the high quality, they feel like new, even though they are more than 60 years old. 
Like you can see, they do have small traces of use, and it is reflected in the price, but they are still so fabulous.
