I began to collect these banners from Nov 2014 till now (Feb 2017).
But initially I was not aware that there are 7 different banners per month so I did miss some of them.

They are:

2 for April 2015
2 for May 2015
1 for June 2015
2 for April 2016

Also, it seems that some of the banners were reused in another month so there are a few duplication in this gallery. I give them different name to note the time. You can download to see it.

When looking back, it's already more than two years, really a long way...

For the banners before 2013 you can see [loli n shota]'s gallery here:

I love collecting these, even if I don't look at them. I feel like E-H is losing some of its identity every time they are changed.
So here I help spreading them with a seedbox. :)

You stole quite a few of my banners and owe me a lot of GP.
