The following shows one of Christian Gobrecht's drawings listed as #13 on page 86 of the article "From the Drawingboard of a Coin Engraver" by Elvira Clain-Stefanelli in the ANA Centennial Anthology side by side with JA1836-2/P3021 recently discovered in the Library Company of Philadelphia. As you can see, they are very similar with Liberty's undraped left upper arm and even has the pointed index finger on Liberty's left hand which holds the pole. The other splasher of this type JA1836-3/P3022 is not quite as close a match. The photo of the drawing is a scan from the ANA Centennial Anthology and the photo of JA1836-2/P3021 is courtesy of the Library Company of Philadelphia.
