No one is going to give you what you want for free.
For awhile I thought about buying advertising on facebook.
still not sure if it would be worth it...
I also thought about showing one of my art works on the advertising display in my city. But it is very expensive.
The question is, do you think art buyers would buy from Facebook adverts?
I have no idea. But what I tried so far hasn't been working( posting in facebook groups, gifting my works...) some people are selling art on facebook. But I would probably have to sell outside of Lithuania...
