Glen, a Dunlop galaxy is the sketch of the day on ASOD today! Dunlop 562 (NGC 1365) in Fornax.

A great feature of this sketch is that is done by the brilliant Australian sketch artist Scott Mellish.
Will make for very interesting comparison other peoples interpretation of the same object.
I've also come across this listing called the "Dunlop 100". You, Glen?
