Using a simple method of inking both sides of a specimen and pressing between folded paper, Joseph Breintnall’s leaf prints show Philadelphia’s local natural beauty. This page from his two volume album has a few feathers in the mix, or are the leaves fallen from birds? 

Breintnall, Joseph, d. 1746.  [Nature prints of leaves]. [ca. 1731-ca. 1744]  2 volumes (368 prints): printer’s ink on paper.
