Hartney, LtCol Harold. Up and At 'Em. Harrisburg, Stackpole Sons, 1940. Sm4to, 7x9", Beige cloth hardcover, former owner pasted book jacket on front cover and spine and book jacket turnin inside front cover. But the wonderful thing about this book is the lengthy personal inscription by Hartney (1st Pursuit Group Commander, WWI) to his comrade Fred Zinn who himself had a colorful and distinguished career as an aviator in WWI. Good condition excepting the book jacket pasting.
