im looking for a certain painting called "the last flower" it's an impressionistic painting that depicts a semi hauling away the last flower to a factory in the distance. the flower is golden and towers over the semi, while everything else is dull and colorless. i need to find this painting. it means so much to me. i can only hope that there is an image of it online :(.
