The June issue of D Magazine is now available. It looks awesome. On page 24 of the "Pulse" section, Paul Milligan and I have another SOUVENIR OF DALLAS comic (click here). For some reason, the webpage is there, but the comic is not. It should be loaded soon...? I don't know.
If you are particularly impatient and you love SOUVENIR OF DALLAS, you could go to the D Magazine Frontburner blog -- hunt down the email address of either Tim Rogers or Eric Celeste. Tell them how much you love this comic, how much you need it, and that the latest isn't online. Be nice. These guys give me money.
Or you could just buy a copy at any local grocery store or bookstore.
**UPDATE (06/10/09)** The comic is finally available on the D Magazine site.
