This is a small card that measures about 3 by 4 inches in size. It’s a membership card for the Woodmen of the World (WOW) Life Insurance Society. It’s dated 1941.
The card was to be used by a member to gain entrance into meetings and rituals of the society. The passwords were to be learned using the WOW book called Ritual (See here for a copy of the book). Interestingly, the previous owner, or someone else, wrote the passwords on the reverse of the card.
