“This artwork is for an upcoming set for our Classic Fantasy range: Giant Spiders. This is going to be a very versatile set with some surprises that we think you'll like. They are currently in the tooling process.” - Wargames Atlantic
And some other information... the box will have more than one size of Spider, with one fitting a 50mm base, and include some sci-fi bits. I expected a victim wrapped in webs but not sci-fi bits. An interesting decision.
I have been using older GW Fantasy spiders and recently got some other spiders from various producers. It is always a balance of cost versus appearance. I know several folks have made excellent spiders out of Halloween toys but I have not had much success with that so far.
Thanks for the tip Sunjester. I have had mixed results with 3D printed models so far though.
