Not so trivial...

Small part of an old postcard I've kept for years because I really like it.
Took a bit of liberty with the colours.
There's a lot of blue in the original.
Must dig out the artist's name...

Anyway, left work at ten pm.
Long day.
Missed out on an evening out with mates.
The joys of on-call.
URTI-ed to the max too.
Boo hiss.

Edit: the artist's name is Jon Cattapan.
