Building better English step by step 1941 vintage reader

The cover of this book is stained and some of the fabric is peeling from the spine as you can see from the photos, but this book is still in good shape for its age. 

There's some slight discoloration on the pages which is common with age, but there are some terrific illustrations in this book for collage and junk Journal artists who enjoy the retro kids book illustrations. 

This book still has good structure. It has 320 pages and measures approximately 8x6 with a 3/4-in spine
