Union Bank of Canada Cheque from 1920 Winnipeg branch

Very difficult to find Union Bank of Canada cheque dated Sep 9, 1920. Drawn on Portage and Garry Wiinipeg branch, Payable to solicitor and cashed in Vancouver.  THIS CHEQUE ALSO HAS 2 ONE  CENT STAMPS ATTACHED FROM THE SAME ERA. Wriiten by Butterworth & Co. Canada Ltd. and payable to W. G. C. Stevenson Esq. This cheque is now 90 years old and drawn on a bank long out of existence. Very few of these have survived as most people just destroy old cheques after so many years. I have no idea what these are worth so I will list buy it now with make an offer. Actual notes from this bank are also scarce and expensive. Don't miss your opportunity to purchase this item.
