An old artwork, reposting in order art was posted on my DA
Description copied from DA(with minor edits):

Comissioned by http://brosmashers.deviantart.com/

Im afraid that due to a lack of extensive communication with the comissioner i cannot confirm whether this is an actual side fic to Fallout Equestria or just a "what if" furthermore the detail description i had been given was quite simplified.
