Curious Prints creates high quality reproductions of your favorite vintage art. The original art is from Kunstformen der Natur (German for Art Forms of Nature), a book of lithographic and autotype prints by German biologist Ernst Haeckel. The art has been scanned and retouched to ensure the highest quality reproduction possible. The art is digitally printed on sustainably produced 100% cotton fiber archival paper. Each print is packaged in a clear sleeve with mat backing and includes an info card about the art. *Optional Magnetic Hanging Frame* The frame set includes 4 sticks, 2 clamping the top of paper and two clamping the bottom. Neodymium magnets are embedded, keeping the art damage free. Our magnets are strong enough to hold the print in the packaging with mat backing so they stay protected while displayed in your shop. The frame set comes with suede hanger attached. Prints are printed in our studio in Austin, Texas. Frames made in China.
