I've got a book that has someones name and address stamped in the front and back cover -- it's very small, smaller than those return address stickers.  I am thinking this book is postable but I've been out of things so long.  It's a wishlisted book.  I thought I'd ask here because I never can seem to find things when I search help -- it's me not the system.

Does anyone know for sure?

Yes.  As long as it is not covering any text. 

Thank you Emily.
