I think that includes every icon from Portal and Portal 2? Ok, some of those are made up, and I know not all the achievement ones are there, but I think it's a good selection.
I know I posted this [link]
test chamber icon guide before and people liked looking at it, so I thought I'd touch it up, add a few icons, make it look nicer. You can now get this as a full sized 2ft by 3ft poster too!

Please respect the work I put into my image. I worked hard to recreate the icons and create my own in the style of the Portal Test Chamber signs. Thanks.
The posters are based off of assets from Portal and Portal 2, owned by Valve. This is a fan work, by a fan, for fans, for the love of the Portal games. There weren't posters out there like this, so the creator made their own and it turns out other people wanted one too.
