The Bluth Family Crest, by Galactic Black
This is probably my most well-known illustration so far - it even “inspired” Hot Topic to make their own version! It was originally inspired from this bit of dialogue from the Arrested Development episode “Pier Pressure”:
Lucille: I need a favor.
Michael: We ought to put that on our family crest.
It initially sold on TeeFury, but since then has been sold by Neuedist.
