This.
I own a closet full of band shirts, but only 2 Maiden shirts (candle middle finger Eddie and The Trooper). Also used to own a Live After Death shirt from 1993 but it fell apart.
Maiden shirts are usually too upfront, too colourful, and often too comic for me. I absolutely love the old Riggs artworks, but many of them look great on posters and flags, less so on shirts (some exceptions of course). I prefer metal shirts in black/white or 2-colour print, and Maiden almost never do those. I will not start about their prices here. Maiden shirts are way too expensive, especially when considering that underground bands release fair-trade shirts in 3% of Maiden's quantity and still make a profit by charging HALF the price....
As for those shirts here: I ain't not patriot / nationalist / flag bearer, so wearing a shirt with a national flag is no option. That being said, Nordics, UK, Netherlands and Italy look quite nice.
Madrid, Paris and Dublin must be bad jokes, they can't be serious about them. Anyone who wears them will never get laid again.
The others are ok I guess. Just another generic heavy metal shirt, not bad, but in no way special.
