Iron Maiden Killers Siraprint blue A

German company Siraprint originated in the late 70's. At the time, many bands experienced issues with merch being held up in customs when entering Germany.
Siraprint sensed an opportunity and began printing shirts for bands to sell in such circumstances.
This shirt came from a bunch of merch found in storage at the original Siraprint warehouse.
Unconfirmed whether Maiden actually gave the official nod for these to be printed, but obviously came close to the band during the tour.
The shirt also appeared in a couple of black versions. Sadly, with the following pics in B&W, we cannot verify which shirt is being worn.

Huge thanks to Nico in Berlin for the shirts and infos.
