Etruscans in Poland?

"The Pomeranian culture, was an Iron Age culture with origins in parts of the area south of the Baltic Sea, from the 7th c. to the 3rd c. BC, which eventually covered most of today's Poland" that has a lot of material culture in common with the Etruscans of Northern Italy (one of the last attested linguistically non-Indo-European people in Europe) and other Mediterranean people of uncertain linguistic affiliation, according to a fairly convincing post at the Old European Culture blog. The most plausible route of the connection is via the Iron Age "Amber Road". But, the artifacts shared by these cultures don't appear in places in between them.
