Victorio,
A capitol 'T' as a Spanish sign usually only means "tesoro"
If a pirate mark it can mean "Tao" or "truth"
There is also a school of thought that says it has a biblical meaning
and that it represents Thomas, one of the 12 Apostles "the doubting one"
If the cross of the T is slanted, the up side indicates the direction to go.
If one side is longer, the long side is the directional.
Not too much more on the "T"
