In an effort to make my mark, I’m working on a splash page image, a logo, and a flag. Something catchy and symbolic, but not already taken. Simple, smart, and understandable. This one about sums it up but I think it may already be in use. 
My personal image for the web page needs to be something as iconic as this pre-war “selfie” by J. Harris Stone. A travelling man like myself.
Also, in the spirit of the early caravanners of a century ago, I am attempting to create a logo, without restricted use, for kindred spirits to fly from their rigs when on the road. This idea struck me several years ago when seeing one of the simple logos from the Society of Primitive Technology on a car in the parking lot of a bookstore far from home.
I knew, when I saw it, there was likely a kindred spirit nearby. Probably someone I know or have very few degrees of separations from. In other words, a person I could probably trust in a pinch.
This was reinforced on me this year while I was driving a thousand miles from home, someone recognized my rig and had his young son hold up an image he knew I would recognize. How cool is that? Icons work to let us know, in this overpopulated yet disjointed world community, who belongs to our tribe. Just as gang members have signs, symbols, and colors, so do law enforcement, military, and fraternal organizations. I’m not saying this is necessarily good, just that it is.
We are tribal at heart for good or ill. I want to put it to work for good.
This photo dates back to a time prior to the completion of my caravan but far enough along to travel across the country. Maybe not iconic, but a document in the life-history of my home.
As there are more and more of us in our circle of fellow travellers, sometimes we are readily recognized.
Sometimes we are not. Maybe we need a flag of our own to fly when we’re lost on the road and maybe not so recognizable. Something like the pennon of the Caravan Club in Europe before the Great War.
I welcome designs from fellow travellers but I hope to create something no matter what. Or maybe it’s just the Saturday evening cocktail talking.
After this ramble, it’s clearly time to get back to work on the bigger problems; seeking knowledge and trying to make my little world a better place.
Preindustrial Craftsmanship 
Something with a wheel. maybe with each spoke a different tool or something.
You leave a wonderful mark just by being who you are, what you are and how you are my friend.
Your mode of transport, your manner of dress, your style say who you are.
You are a living symbol. Do you really need another?
Yes I know before you remind me that The Flying Tortoise has a cartoon avitar…

Thanks… and well said. As I noted, it’s just a ramble. I am selling some more leather work and such lately and it has been pointed out by several that I need to mark it in some way. Some don’t even want to buy something if it isn’t “signed” in some way.
Ah yes… it would be good to have something for your leather work…
The old tool makers used semiotic marks, I believe because most people were illiterate. Addis actually had the mason’s mark (it looks like two x’s, a “double cross”) Sorby used a Punchinello from Punch & Judy. Wade & Butcher used a Maltese cross and an arrow (armorers liked arrows). Nearly impossible to find a simple mark that hasn’t been used by somebody.
I’ve never seen the mason’s mark with a bisague included, must be a carpenter’s mark. Where did you find that?
The broad arrow is used for the British military. Simple as can be. Every variation on the dividers and square is taken by something masonic or the old carpenters. The mason-bisague is from the compagnonnage l’art du trait. I’ve come up with designs that end up looking like something from Earth First, the freemasons, the MoD armorers, and other variations. I don’t want writing either. Totally semiotic. I may steal something old and unused like a head knife and square.
Another question; in the J. Harris stone photo, what’s that crank wheel below the deck for? I’ve seen those before, but never puzzled out what they do.
That’s the wagon equivalent of the emergency brake.
