From what I had read in the mentioned study below, this bottle was no longer Dr. Pitcher's Castoria! The original Dr. Pitcher's bottles are a bit more scarce.
Please Google a terrific PDF titled: Pitcher's and Fletcher's Castoria As Uncommon Study of Common Bottles by Bill Lockhart, Beau Schreiver, Carol Serr, and Bill Lindsey with contributions by Joe Widman. It is at www.sha.org, search bottles, pdfiles, Castorial History.
"When Samuel Pitcher invented Castoria about 1867, he set in motion a series of events that would lead to several variations in bottle embossing, a series of law suits, and an incredibly popular remedy."
