Books

….as in thick (and thin) photo books. 
Mono Monday’s theme is “thick”.  These  and many others were on my bookcase, I thought they’d work as mono quite well.  The two thicker ones are around 200 pages the one on the middle is just short of 100 pages.
I suppose the stripes in the background drapes are thick while others and narrower. 

Another warm day, 27°.
