So who did the art for the merch?

So in my never-ending quest to find and give love and credit to all Riot artists,I'd love to find out who did some of the art for the Riot merch store. I know most of the the posters are Su-ke's work with some contributions from Artgerm,~~ but I'm not sure about the sun v. moon or the rengar v Kha'zix posters.~~(Best i could come up with is perhaps jeff woo's team ? ) Nevermind it is his work Psst put these up on the store too!) On that note i'd love if you put some work of David Rapoza's up in the merch store <3

Its even worse with the t-shirts, as i put my foot in my mouth thinking the kog'maw and thresh shirts were inkinesss' work :X( they weren't, i'm just completely lost with shirt artists) https://d31860yg36552c.cloudfront.net/media/catalog/product/k/o/kog_maw-tee.jpg https://d31860yg36552c.cloudfront.net/media/catalog/product/t/h/thresh_men_s-tee.jpg http://fc06.deviantart.net/fs70/f/2014/257/1/4/149a0feb2b18d8086cb6ba32df197b38-d7z7lqr.jpg (I guess my artistic taste isn't quite as strong as i thought >.<)

Also can't count out sculptors, whose mind is behind the thresh statue and the figures?

As much as I think it would be a compliment of how highly a random guy thinks of you to ask if you had a hand in designing merch for the biggest game in the world, I'm not sure they would think that way after seeing him spamming the twitters asking many different artists :\ Thanks for any help anyone can provide :)
