Three post office sourvenir covers with community welfare Australia 1980 stamp set including the Salvation Army stamp. First day cancel. Kangaroo, Koala and Kookaburra. Local postmark: Burwood, likely a local connoisseur. Unlisted cachet in the SA FDC catalogue. Although the souvenir covers are common, these covers with FD cancel are likely very rare, as I’ve only seen one of these before with the SA stamp.
