There are two different inner sleeves availabe. All show the black and white photography on one side and the antenna graphic (with/by Emil Schult) on the other side. But some early printings do not include the lyrics which were added later. This version has inner sleeves with printed lyrics on them. The very early issue without lyrics on the inner sleeves can be found here: https://www.discogs.com/Kraftwerk-Radio-Aktivität/release/15895727

Some initial copies had a sheet of 16 yellow stickers and one of the yellow stickers on front. Only the first edition was released with the small “HörZu” sticker on front cover. On later editions this was printed.

Some early pressing had a 12″x12″ b/w insert “German Rock Paradise” with LP cover images of mostly German bands (Triumvirat, Kraftwerk, Can, Tanned Leather, Jail, Eloy, Gebrüder Engel, Sweet Smoke).
