Favorite Family Heirlooms

I have a sampler my great, great grandmother embroiderd in 1859 as a young bride in Prussia before she immigrated.
I have my great, great grandfather's (not the one married to the aforementioned gggm) army discharge from 1865. I also have a photo of him in uniform from 1863-64, and his G.A.R. badge. Also a New York Gettysburg Veteran medal from when he attended the dedication of the New York monument there.

*Edit - photos added.

Take a good look at your sampler.
If you haven't noticed this yet, there are two mistakes.
They aren't accidental. This was a common practice with young ladies who completed these as part of a "finishing" school.
This could have been a formal school or just a couple of ladies with some younger girls learning how to properly sew, cook, clean and how to be a wife.
The reason for the mistake is that "only god is perfect, man will make a mistake".
BTW, the mistakes are that the upper case letter I is missing and the letter Z is out of place.
Also, this is a very American thing, European samplers may not have this.
