Geekadelphia just posted about HOOT (the literary magazine on postcard). They included an image of the postcard I designed for HOOT’s May issue- check out the post!
And, while going back in time to subscribe to HOOT is worthy of the Tardis (as Geekadelphia implies), you can just get all of their back issues here (their Etsy shop) and subscribe in time to receive July’s issue in the mail! Save the Tardis for something else- like witnessing Socrates drinking his hemlock, meeting Sitting Bull, or jumping to the future to find out what the Singularity is all about.
