1) What do you mean by "you really did not want to see this come out, but good job"???
2) He was used as a logo, and in adds, so for some who take those type of things as "first appearances", one of those appearances might be of value. I would personally use Hip Flask #1 (Unnatural Selection) over the other things.
"The character of Hip Flask first appeared in a number of advertisements for Comicraft comic book fonts in the late 1990s in which he was originally depicted as a private detective (this has since changed in the pages of his own comics). "
I meant: Good job picking this comic as a speculation... It has been under wraps ! I agree the first Story or full appearence is Hip Flask #1 (Unnatural Selection)
