Book published in 1859 teaches you how to make hand shadows

Hand Shadows To Be Thrown Upon The Wall is a book written by Henry Bursill and originally published in 1859. From the preface: "Of course the Shadows are not to be reproduced perfectly, on one trial only but I believe that in each case I have drawn the due position of the fingers with such care, that the most difficult subject may be accomplished after a few minutes." I just did a tortoise! Yay!
