The cost of the bigger-than-life-size statue (about 1.3x) is ~$25,000 (I'm happy to show you the receipts) Shipping is ~$6,000 (it's "art" shipment so it's more expensive). + Installation at the park + Permits from city gov + Costs of the unveiling event
A 501c3 (not my own, but a tech-culture magazine "The Mars Review of Books") is sponsoring the project, so yea all donations are tax deductible.
I've personally paid ~$10,000 (again, I'm happy to show receipts) to get the design of the statue + website - and I made it all open-source so anyone can 3D print their own statue, for free.
Let me know if you have more questions.
