They are decals. I don't recall the manufacturer exactly but I found them on Etsy.

You can also find great wall decals at whatisblik.com.

This looks similar to Uppercase Living's vinyl expressions that I sell. There is a botanical collection which you can view here: http://jeand.uppercaseliving.net/Category.m?CategoryId=226&CatalogId=&DesignId=&ItemId=&CurrentPage=1
I have the "Out on a limb" expression in my home. It is very similar to the photo above. The direct link for "Out on a limb" is: http://jeand.uppercaseliving.net/DesignItems.m?CategoryId=226&CatalogId=&DesignId=2614&ItemId=&CurrentPage=3
All of our vinyl comes in your choice of over 50 colors.
