Mono Monday: Corners

This will probably annoy a lot of people, or give them the shivers like chalk scratching on a blackboard.  The kids of today probably would have no idea of that sound. 

I prefer the corners of the pages of my books not to be dog earred.  Hence the book mark that you can see here.

Thanks to Random-angel for hosting.

This was a book was published in 1961 which makes it 60 years old.  Does that make it an antique I wonder.
