Matagal ko na to nakikita pero wala pumapansin so I think it would be better to sell your painting to a different section ng forum. Try to make a thread sa
Goods section ng Economy board, baka meron nagkainteres sa painting mo.
Anyways, it's nice to a fellow artist here
wala akong masyadong alam sa painting pano ba malalaman yung authenticity ng painting?
Dapat manggagaling sa mismong artist yung authentication. How? The creator must include
Certicate of Authenticity inside the packaging either worldwide or local shipping. That certificate include the medium used and other stuff like title or stories behind the artwork.
