Astor brand - would you say it is Australian?
Well, there is a small cute Koala in its illustration
appropriately wrapped around the trunk of the "T".
I cannot say for certain at this stage (I would
have to find the proof) but I think there may also
be an Astor brand darning card lurking somewhere
in a box in my household (we have just moved house
and I will need more time to uncover the
particular darning card that I think I
might have - you will have to stay
tuned for further developments!)
