vintage farming agriculture horticulture textbooks, 1930s 50s books old green cloth covers

Lot of seven very worn vintage farm books and textbooks, 1930s, 40s and 50s. These have lived in a barn for over half a century, and they're somewhat musty, with soil and stains on pages and covers. I love the covers, shades of green and grey. They'd look so good in a display together!
