In some previous posts I've shown how McGill's cards produced for the publishers E.S. were copied by another publishing company - E.L.P. Co - in the early 1900s.
I have come across another instance of this happening much later and on a different continent. Green's Souvenirs of Katoomba, New South Wales in Australia have copied several of McGill's cards - having them redrawn with some slight variations by an unknown artist.
Inter-Art and Constance originals have been used but in what seems a random selection. I have no idea how many they produced but these are the five examples I've found so far. I'm guessing they date from the 1950s as none of them are postmarked.
