These are the re-releases from last week's Hitlists, plus the Pilot and Ouroborous issues which were digitally released a while ago. That constitutes the totality of "Hip Flask" - according to  http://comicbookdb.com/title.php?ID=8245  , at any rate.

Note that the Pilot is identical to the one included in the "Elephantmen" pack (  http://piratebayproxy.live/torrent/8968948  ) under its original release name "Elephantmen 009.5 (2007) (Digital) (JK-Empire)"; the reason being that it says "Elephantmen" on the cover, while some constituent shorts were originally released under the "Hip Flask" banner proper and were thus needed to complete this pack. Keep one, kill the other, depending on which of those considerations wins out for you! :P
