How can I contact an Artist?

[Joyita]

I have a cultural page in Facebook, it is a magazine. I would like to contact Artists as Paul Grand to ask permission to post their works on my page. Maybe you need the address of my page, well, just let me know.
Thanks so much for your help,
Selene Natera Alfonsin

If it's digital, the norm is all about common courtesy and giving proper credits. Cite your source and when you're asked to take it down which I highly doubt, then take it down.
