This unlisted Canadian FDC was just observed on Ebay. It was issued by the Brockville Stamp club and must be extremely RARE, I have not seen it before!!! It was sold August 2020 in a lot for CA$ 220. NB! This is a reference cover – not in my collection (the picture is edited from another Brockville FDC as only the upper half of the Salvation Army cover was visible in the original listing).
