As a life-long booklover you've probably been in a library or two before the advent of bar code scanners or computerized catalogs, when books were still date-stamped. Take yourself back to that simpler time - when the library card system was meticulously and successfully patrolled by stalwart librarians - via a pair of Library Card Socks. These comfy crew socks (75% cotton, 10% nylon, 10% polyester, 5% spandex) are great gifts for anyone who remembers the library card system or who labored tirelessly to make it work. Available in small (fits most women) or large (fits most men). Choose from yellow, turquoise, or dark teal.
