With @smallpressexpo.bsky.social coming up, I thought I’d share a story about why it means so much to me. Twelve years ago, SPX was the last place my dad ever went. Like, ever.
SPX logo banner with that reads SPX Sept. 13th and 14th 2025! The illustration on it shows several people with empty word balloons above them.

Hi #portfolioday! I’m Oliver, a writer and colorist of things like A Ghost Arm Made of Angry Ghosts and The Monuments. I have also colored many shorts in Ringo and Ignatz nominated anthologies.

I’m currently looking for writing gigs and/or color work on any comic shorts or covers.

Six panels showing a building over time. Sometimes it’s fine, sometimes it’s on fire, other times it’s run down. Six panels showing a teen with powers melting.

I stopped by @fantomcomics.bsky.social and picked up the trade of the amazingly weird series The Pedestrian by @seanvongorman.bsky.social, @joeyesposito.bsky.social, Joshua Jensen, and Shawn Lee. It’s so good! Go buy a copy. No wait, buy three copies! One to read and two more to also read.
