Can I Get Help With A #111 5c Blanc ID?

In my opinion a forum is not like chit-chatting with someone standing next to you nor is it typically 'brain-storming'.

Writing coherent posts, staying mostly on-topic, sticking to the thread titles are all things which help make the threads 'stand the test of time' AND generate the most responses.

You aren't breaking any rules and you are welcome to keep posting the way you do, I was just trying to help. Part of my job in the community is to help (both with philatelic questions and forum etiquette and organization), keep the content as accurate as we can and foster friendliness.

Don,
I have nothing but respect for you and the community
Unfortunately for me this is the only place I know to do this (I'm loyal I started here :)
If I see something I ask about it, just to interact
I'm not very good at tech or writing letters/posts but trying to get better
I learn as I go

Could someone work with me to present this properly?
I need a tough nut to crack....but someone that has a little understanding and patience
As my methods are different and this will take some time
I don't think it would take long to convince just iron out details
Please, if I'm wrong I'll put a dunce cap as my avatar and take a month off to just read
I can prove it just not present it to satisfy but I think I can clear up a few things
Especially if I get to see this "devil's mask" I see things different
Mouchon was a brilliant passionate artist no wonder he would be so upset about that claim
Am I on my own to prove it fair enough
But some help along the way maybe
A title-I don't know what to put for this situation
How to embed video-only got a short one

Is there a book specifically on the blanc series?
Also if you had an identifier is there a sheet (like for penny blacks) that's available?
