Charles Fetherolf (Giants in the Earth, Sons of Cain, District Comics, Once Upon a Time Machine’s “The Crossing”) has a table at the always-fun Museum of Comic and Cartoon Art (MoCCA) Arts Festival this weekend (Saturday April 6 & Sunday April 7, 11am-6pm). You’ll find him at Table C74, just ahead and a bit to your right as you walk in the main entrance.
On Saturday All weekend!, he’ll be joined by Andrew Carl (editor of OUaTM, writer of “John Henry”) with a hefty pile of Once Upon a Time Machines to sell & sign together.
So if you can, head to the 69th Regiment Armory (68 Lexington Avenue, between E. 25th & E. 26th Streets) in Manhattan, NY, and say hi! Table C74! 
Once Upon a Time Machine 
Wow, it’s wonderful festival. I like the design.
