This is a rare promotional 2 cassette tape set from late 1980's in the original factory sealed packaging titled “PolyGram Presents an Introduction to Fiction” featuring the bands Die Warzau and Eat. The enclosed 2 cassette tapes are inside the original factory sealed promotional  packaging.  The shrink wrap sealing is in very good shape, but the plastic promo case is slightly indented on the top and bottom. See Photos for details and actual condition.
