How'd I miss this?! I'm right into
Trigan Empire, no matter who the artist was (though Lawrence and Ron Embleton are the top picks).
There's a new
complete limited edition series of these coming out - only 500 or so of each, I think I heard, but they're excruciatingly expensive

.
I've replaced some of my old
Look and Learn issues, but not many - my mother gave them all away to a neighbour, who no doubt chucked them out!
