EDPA Site Banners Size Suggestions

We can support various sizes, but I would recommend horizontal vs. vertical.
Below are some example banners that we can have on the site. We can also work with sponsors if that want something more custom.
Overall the banners should be additive vs a full page etc. Not unless that want to sponsor a news story or member blog. That would be more of a full page take over. Then we can drive users to the full page take over on social and email.
