I'm looking for the font except for that big 'H' which is not part of Angus' regular font.

The closest I got was "SwingSet BB" and "Hero Of Fools".
I found Angus Oblong's exact font years ago once and then I never saw it again.

Out of curiosity ... what is an Angus Oblong? Is it edible? And if not, what can possibly be the use of it

Nah, he's an illustrator who made some books and had a cartoon based on one of them.

I and thus you too, see three different g's as a starter. Then when you look at the other letters we see that they are all different. Which makes me and should make you, wonder ... is this a font?

You're right about that, I remember he mentioned using a font for his digital works though.
This one is a traditional but thought somebody could find a similarity to an existing font.
I've saw it as well years before and never found it again.

Right now this is the best I'm finding so far.

I believe it's Oblong Regular, if I'm not mistaken. Too bad you have to buy it on the Angus Oblong website.
