I want to do some marketing for bitcoins and therefore want to produce pictures, flyers, T-Shirts etc.
While the orginal Bitcoin Logo / Symbol (https://commons.wikimedia.org/wiki/File ... n_logo.svg
) seems to be in the public domain (is it really?) al lot of derived artwork pretends to be copyright protected (e.g. https://www.fotolia.com/tag/bitcoin
) even by sites, that don't accept Bitcoin as a payment method (will not! buy there).
1.) Are there free (trustwothy) Bicoin logo collections?
2.) Are there commercial (copyright) sites, that at least accept Bitcoin?
Thanks for your help!
