I just picked up a Valor #3 to complete my run of this five issue title. While I'm trying to finish off longish runs of EC's 'New Trend' titles like Two-Fisted Tales (have 18 of 24), Weird Fantasy (13 of 22) and Weird Science (16 of 22), I like to also have one of the short 'New Direction' titles on the go to give me a chance of finishing something off sooner rather than later. Finding ECs in nice midgrade seems to be harder than finding low grade copies or high grade copies, thanks to the Gaines file copies. I bought my first Valor in December 2012, so about 18 months for this 5 book run.
The run before that was Aces High (also 18 months over 2010 - 11):
I think the next run will be Piracy (7 issues), and I'll keep working away at Mad 1 - 10 (7 of those so far). The only other EC run I've completed is the 15 issue Frontline Combat (two and a half years for that one, and now one of my favourite comic series):
Much as I love the right 'one off' book in my collection, there's something especially nice about finishing off a run.
