Help dating - 1868?

[Laura]

I recently bought a pattern catalogue that is not dated. The latest date mentioned in an advertisement is May 1868. The skirts have fullness toward the back and drapery & overskirts, foreshadowing the early bustle. I'm pretty certain the catalogue dates to within a few years of 1868, but I would really appreciate help narrowing down the date as much as possible.

Here are several images to help.

Thanks!

Had you not said what you did but just showed me the pics I would have guessed 1868-1872
