I finally feel up to posting these adorable vintage bird illustrations. They come from a variety of antique sources and are in the public domain with no known copyrights. I hope you enjoy!
Here is a vintage illustration of bird bills and beaks from an antique birding manual. Top is the original, bottom is the print friendly black and white version. Enjoy!
Here is an illustration of vintage bird eggs, the top is the original, the bottom is the editable easy print (PNG transparent background) version (you can print it onto a book page if you like). Enjoy!
Here is a vintage image of a typographic owl (what I call an owl made out of words). The top is the original, the bottom has the background removed and was edited for printing. Enjoy!
