No insurance contract heretofore or hereafter issued and which is otherwise valid shall be rendered invalid by reason of the apparent execution thereof on behalf of the insurer by the imprinted facsimile signature of an individual not authorized so to execute as of the date of the policy.
Any company which issues a bond as surety with facsimile signature under the law of this state shall, in any proceeding to enforce the liability which it has assumed to incur, be estopped to deny its corporate power to execute such instrument or assume such liability.
