Stjärnbragder (Star Exploits) was published by Allers Press and was a comic magazine with different (American) comic heroes.
They were published in 1952 and 1953. Prins Valiant appears in number 1, 2 (1952) and 7, 8,9,10,12 and 14 (1953).
These Phantom magazines are also published by Hethke-Verlag in Germany, Skipper Skræk magazine from Danmark
and Kippari Kalle magazine by Sanoma in Finland. They are all using the same covers.
Value must be high, I guess around 25 Euro per book.
