Hi John, here you have the updates.
#104, #105, #106 and #107 with different fonts.
I think that entry #92 and #107 has a more readable font, but you choose.
Why? because in lower case the "a" maybe can confuse with "o" i think is not different enough.
But maybe for signs from distance, like highway.
Just my thoughts.
I like
#104, #105 and #106 too!
You choose the best for you.
Thank you and best regards, Fernando.
