Cars and Crumpets : This story exists in 3 different versions with 3 different titles in 3 different versions : As Cars and Crumpets it was published in Teenage Sex No 6 : The ladies are called Britta and Mirja.
The story text tells that Mirja is from Greenland,means that she is native Inuit. This circumstance is possible, because Greenland is a part of Denmark, where this color climax set was produced in the late 70s. (Actual many people from Greenland live in Denmark.)
Accordingly Britta, even if she has this Inuit-look, should be a real native Danish and Caucasian lady.
