Victorian Calling Cards

Hi,
I've never had these before so I was quite excited to purchase a bag of them today. Some of them have 2 different names on them, one hidden inside and one on the back. I found a site that has lots of information about these cards but I didn't find anything on why there would be 2 different names, so I'm hoping someone will know the answer. Also, the one is photo #4 - what does it say?
Any information appreciated.
thanks for looking.

 

Here is my favourite one, plus a a close-up of some of them

 

Xlated from German:
For diligence and obedience

 

Thank-you spring!

 

WOW!!!

 

VERY nice!!!!!

 

CXGIRL. Speaking of coincidence - Great!

Please post that URL you found. I'm running between appointments today and until
Wednesday when I hope to get a GeekSquad'er in here.

And, as normal, I cannot immediately put my hands on the one I found a few days ago while going through some 1800s, early 1900s family records.
A Christmas card I believe the same size. About 2x3. Correct? I was surprised how it is put together. About 6 or more different layers, in different sizes and shapes. And one thought of the customs back then, if I'm right.

Inside, hand written to my maternal grandparents - "To Mr. and Mrs. XXXX from Mr. and Mrs. YYYY."

And one other question, if I may. How was it delivered? Mail, or dropped off? In an envelope? Were those included in your find? Or they didn't use them?

I hope you don't mind answering questions when you came looking for answers.

Thank you.

 

Lucky you to have found one from your family TOG! Yes, I should have put these sites in my first post, sorry about that - they are on the bottom of this post.

By the beginning of the 19th century, the etiquette of calling was a firmly established ritual in society, and the calling card an essential part of introductions, invitations and visits. Calling cards evolved in England as a way for people to get into the elite social circle, and for those already there to keep out the unwanted. Calling cards could keep social aspirants at a distance until they could be properly screened.

The cards were delivered by hand - I have found some with envelopes but I don't know if they all came with envelopes and there were no envelopes with mine.
Mine range in size from 1 3/4" x 2 1/2" - 2 3/4" x 4" and have different layers, some have a piece/flap that lifts up to uncover a name or saying (Spring translated the one for me)
