I am pleased with how this turned out, they need a base of some kind and I havent been able to find just the right one, but that rock in the photo is just about right, so I may very well make a mold of it and cast it in acid stained concrete so these can be mounted to them and be securely standing upright. Cut stone is very expensive, about $150 each plus shipping, the landscaping blocks you see out there are all concrete and the wrong size and so forth, so it leaves making them myself.
I will probably have these winged griffins with a base for $375
They are black resin, primed and painted gloss black, the wings attached with stainless steel machine screws, along with same for attaching to the base.
They can be done without the wings too, most of the few originals left in NYC lack their wings- they were broken off.
