For your consideration, here is the Vintage 1933 Champion Arithmetics Grade Six Mathematics Math Text Book, published by the Row, Peterson and Company, 512 pages.  It measures 7 1/2 by 5 5/8 inches.  It has very little wear on the covers.  There is some normal tanning of the pages.  

It has a nice look to it.  I like it for the cover design.  It might display nicely.  It will be mailed in a box for protection.  Item pictured is the actual item up for sale and comes from a non-smoking household.  (493.335m-1.5sb)
