hi, i’m looking for some ideas for creating icons and symbols something like that, my friend got this book called “Lingua Grafica”, very excellent one, but since it’s out of stock now, i could hardly get a copy for my own. Could anyone suggest another good reference books too? 
I don’t know of any, but you can get the above mentioned book here…
Or here…
They both have it in stock.
any other similar books for this kind too?
