Needs suggestions for promoting my Blender art exhibition

Hey guys,

             I'm planning to organize a grand exhibition of Blender generated artworks by the coming July. The exhibition will include some extraordinary works from eastern style, abstract style, and western style. 


             As we all know that, marketing is an inevitable thing. Without proper promotion, there won't be people to take part in any programme. Last year, I conducted my very first exhibition. But due to lack of promotion, I didn't get much publicity and engagement that time. 


             So that, I'm seriously thinking about applying some good promotional tactics for my upcoming exhibition everywhere to reach a wide audience and hope to get those people attending my exhibition.


What about outdoor advertising?I think outdoor advertising is a great way to let more people know that you I’m hosting an exhibition. What’s your opinion? Awaiting your suggestions and comments.

Thanks in advance.
