Unless otherwise stated, nothing on this blog was made by me.*
I vaguely remember the posters you’re talking about, but I don’t feel like digging through four and a half years worth of posts to find them. If they’re not sourced—which they should be, unless I reblogged them from someone who didn’t; but on posts before 2011-ish Tumblr tends to have stripped the source attribution, which is terrible—it would be easier to find the source using a reverse image search.
* Which is to say, nothing but that gif, and this.
