Hand signals for a signature
Illiterate people can sign official documents with “three crosses” as a hand sign - here there are × -variants next to + -forms. Even today, a signature must be certified in this form (for example: "A signature that is not made with the name signature, but with a simple hand sign - the most famous are three crosses - requires certification by a notary" § 126 dBGB).
