Vignette style CdV for dating please

[JenB]

Please can I have a date for this rather nice CdV.

Sadly, in common with some others from the same group of CdV's this has been rather clumsily trimmed although I suspect that the top left corner retains the original rounding.

I have several other Gibsons with rounded corners which have been dated to mid-late 1860's, (see links on this thread https://www.rootschat.com/forum/index.php?topic=785179.msg6402780#msg6402780 )
which (with my meagre knowledge) is what I would have expected from the design on the reverse 

Any advice appreciated as always.

Hi Jen...The photo corners do looked to be round and the oval vignette was popular in the 1870s. So I would say mid-late decade.

Carol, thanks very much.

I had really thought that, because of the simplicity of the back of the card, it might be late 1860's.

I will have to get better at this dating business!
