Earliest Use Of Judaic Star Of David As A Cancel?

What is the earliest reported use of the 6-pointed Star of David used as a cancel on a stamp or letter, but specifically as a Judaic symbol, i.e., not the stylized masonic cancel of simiilar design that is found on U.S. letters of the 1850s (Chicopee, Massachusetts) or the negative cork killer used in the 1860s (New Haven, Connecticut)?

I have a revenue usage from 1864, but I'm curious as to whether there are postal examples that predate it.

Thanks.
