Signs do not use the same texture for front and back

Can confirm, though @unknown already confirmed their report so thats good.

Oh yeah, sorry, shouldn't have done that, my bad.

I'm guessing that the front texture has had the contrast deliberately lowered, so that the text is easier to read. I don't know for certain that it's intentional though.

It's to be more readable for text, the contrast is lowered on the front. 

now that you can write on both sides it would be appropriate to change it
