So, I could use some help. I saved this image from a Dazzlings themed Ask Blog on Tumbler years ago (it was in response to a question of mine in fact, insinuating that Dagi and Starswirl were a thing), and for the life of me I cannot remember what it was called, who the artist was, and I can't seem to track down other images from that blog.

Any assistance anyone can offer will be greatly appreciated, especially if anyone else knows of what blog I am talking about and can either tag this appropriately, provide an actual source, or at least inform us on whether or not it has survived the ravages of time and changing site regulations.

Thank you for your time.
