[The Australian Panther]

Thanks Lyons. A very idiosyncratic book.
Cyril Frederick Austin

Died in WW1
That would explain why there appears to be no other work by this duo.
The artist, (signed) was
AUSTIN, Hilda Alice 1878-1972 [Sister]
By the date, she would have been 26 when this was published.
It's not often appreciated but war has taken from us many creative people before their time.
His whole military story is well worth sober reading.
Use the link above.
Note,
[An extract from the Battalion War Diaries for the 13th November 1914, shows Cyril and 3 others from the Artist Rifles, were posted to the 2nd Battalion, TQRWS Regiment as probationary 2nd Lieutenants.]
What was 'the artists rifles' I wonder?
