St John Ambulance First Aid 1928 book

This mini antiquarian book is a copyright from 1928 after WW1 but before WW2. It measures 5.2" x 4" The outside spine of the book is loose but the pages are all still intact. Some of the pages are yellowed which is normal for its age. ***Please see pictures for condition*** I rate it an 8/10. The name of the original owner is stamped on the inside front and back. It describes first aid in wonderful concise detail.
