I just listed a lovely and hard to find vintage health reader called Just Ten Minutes: A Health Story. This 1926 school book has gorgeous silhouette style illustrations by Jessie Gillespie. I have seen Jessie Gillespie's illustrations in The Birds' Christmas Carol (Kate Douglas Wiggin). I looked for more information, and found that she was born in Brooklyn, New York in 1888 and lived until 1926. I am still looking for more biographical information on this illustrator, so please add a comment if you have more information. Thanks!
