Wyo. Stat. § 21-13-719: Use of facsimile signatures.

Any person herein authorized or permitted to sign any bonds or interest coupons, may utilize a facsimile signature in lieu of his manual signature provided that the signature on the certificate required by section 8, article 16, of the constitution shall be manually executed. Such officer may adopt as and for his own signature the facsimile signature of his predecessor in office in the event that such facsimile signature, having been executed by an officer then authorized to do so, appears upon the bonds or coupons, if any. It shall not be necessary for such officer to file any certificate with the secretary of state or any other board or officer.
