Personally, I would want the same size, same color, same model as the original.
Besides that, I would not vote for genuine reproductions whenever plain paper is involved.
Better to have those remade in waterproof plastic, so they don't fade and deteriorate like their ancestors.
No doubt that some hard-core purists have different ideas about that, but that's just my personal take on this.
I would not, however, want to see aluminum stickers replaced by plastic. That's would not be an improvement
