Classic Album Cover Stamps

I've never understood stamp collecting. I know it's a form of art collecting, but I (usually) think of it as what most people would consider corporate art. It's a company telling you what's beautiful. That was until the Simpsons stamps some may even say the Elvis stamp made collecting popular. I don't judge it's just not for me.

I may have to change my thoughts with these stamps.

But since when is anything by Coldplay classic? Let It Bleed I agree with, but Coldplay. That's a stretch.
