Pop Express was a Yugoslav music magazine that got published in Zagreb for less than a year during the 1969-1970 time frame.

[1] It was published by Centar za kulturnu djelatnost omladine Zagreba (Center for Cultural Activity of Zagreb Youth),[1] every second Monday in a month.

It featured that distinct graphic design, but it also covered topics that weren't strictly related to music.

[...] Pop Express should be mentioned for another interesting thing, it was probably [...] the only [Yugoslav] music magazine to have one of its issues banned [by the authorities].

[...] The 13th issue was banned, not because of a written piece about music, but because of a letter to the editor sent in by a reader.
