I dont think Kittyhawk and Tom_Swan have any intention of releasing them in the near future, but it would be nice if there could eventually be somewhere with the whole "theJar" archive on it. Now that this is a new comic, some people might have started reading in the post-jar stage and therefore wouldn't even know if it's once legendary existence.
summary: not likely but i think you'd probably have to ask the 2 people that are actually in control...
Just go to Archive.org to see the old comics. Though a lot of them are broken and unsaved so you get a lot of un-accessable images, but i'm sure you could peice somthing together if you wanted... Pervert.
