My parents just bought a townhouse so my mom wanted some help shopping and I was happy to oblige. We went to Hom Furniture and I found a surprising amount of decor that could be considered Neo-Victorian or Steampunk. I took some pictures on my phone of my favorite items. This particular Hom store also had a pseudo-balcony that was lined with cupboards that looked like library shelves so it helped at to the Steampunk feeling due to all the books in the interior design.
This table below and the side table set above really caught my eye.
But most of what I found was wall art like the pieces below.
