My original tumblr post was here. This image was researched by Bacchus at ErosBlog as part of the “Δ commission.” The research was originally published at Hedonix as “Δ 054 – Chained Monster And Mate.” Here is what Bacchus found.

This “Frankenstein and his bride” image is watermarked “Scott Blair Art”. The source Tumblr blog in the image’s Tumblr chain of attribution is ScottBlairArt, the “artwork blog of modern pinup and sketch artist Scott Blair.” The image appears there under the name Monster and Mate.

Blair’s website is at ScottBlairArt.com. Blair’s “about” page there reveals:

Scott Blair is a freelance illustrator currently located in Tampa, Florida. He graduated in 2000 from Middle Tennessee State University with a Bachelor’s Degree in Graphic Design – focusing on illustration. Originally working traditionally in acrylic paints, Scott made the switch to digital painting in 2005. He takes his original drawings, scans them into Photoshop and paints them digitally using a Wacom pad.

In 2007, Scott shot a Bettie Page inspired photo shoot, after which he realized that creating modern pin-up art was his new passion. Since then, he has been creating custom pin-up artworks for commercial and private clients…

The artist’s DeviantArt page includes two more Bride-themed artworks (here and here).
