G'day Panther.
I realise it's a minefield but could you explain further about how copyright relates to comic books. Is it, for example, seventy years after the deaths of the writer, penciller and inker? (and the person who puts the words in the balloons too?)
As for characters, is it seventy years after the death of the creator eg Jerry Siegel died 1996 so Superman enters the PD in 2066? (except of course, there's the very welcome 95-year rule in the US - so Action Comics no.1 itself will become available in 2033 - not so long to wait - and, indeed, the first Hal Foster Tarzan strips will be free on Jan 1st, 2025)
Or so I believe - but like I say, a minefield
