Bogart Creek has a Patreon Page:

I've been drawing Bogart Creek for few years now and have had a lot of luck. Having said that, if you really, really want to support my comic, who am I to stand in your way?

There's a sample below of the type of exclusive content you'll enjoy as a Tier 2 member on my Patron account.

 

Thanks for your consideration - I'll see you in the funny pages.
- Derek
