Transfer of Personal Property. The capital stock of stock corporations shall be divided into shares for which certificates signed by the president or vice president, countersigned by the secretary or clerk and sealed with the seal of the corporation, shall be issued in accordance with the bylaws. Shares of stock so issued are personal and may be transferred by delivery of the certificate endorsed by the owner or his attorney-in-fact or other person legally authorized to make the transfer. No transfer, however, shall be valid, except as between the parties, until the transfer is entered and noted upon the books of the corporation so as to show the names of the parties to the transaction, the date of the transfer, the number of the certificate, and the number of shares transferred.
