Oh hay look, Tumblr found my comic somewhere. Title page is missing, it’s actually called “On The Importance of Space Travel”, not “Show and Tell”. It’s published as part of Volume 5 of an amazing short story anthology called “Flight” which you can find here :)
…Man, I still remember working on those pages, in the dark of a Montreal night one February. Good times.
