This is a scott 2544A, $10.75 Express mail (Space shuttle). I removed it from the sealed cardboard package issued by the USPS. Has anyone ever seen these red threads on the back of a stamp? They seem to be embedded in the gum, but they might be in the paper. Is this normal for this issue? There is no mention in the Scott Specialized about it.
Incidentally, the correct philatelic term for paper with visible security fibres in it is "Granite Paper". It is called so, as the paper looks like the rock, granite.

I understand that, but this one looks like someone just took a red pen and drew random lines on the back of the stamp. Doesn't look like "standard" granite paper at all.
