There is no official picture of Salomón Pico only a picture of his Governor Cousin Pío Pico which sometimes gets mistaken for Salomón. So we have to use our brains that God gave us to construct what he looks like.
Foot Note: This is where The Foreign Films end. My fan theory regarding The Son Of Zorro (1973) is that this particular character is a bastard son who was left behind hence his name being different and the title of the film.
Foote Note: I am fully aware that the first 3 Mexican made films are not connected to the European films but in my own fan theory they very well could be.
The different Zorro's who are not Diego, I view them as cousins. Regarding the prequels that take place in the 1600s I would say those are ancestors. Just a fan theory of mine to make a timeline for these loose films.
However, Indy does have some signs of greed. In Temple Of Doom, which takes place in 1935 before Raiders, which takes place in 1936, he wants the Shankara Stones for himself at first.
Indy does display signs of greed similar to Dobbs. Hence his phrase.... "fortune and glory". He does develop as a less greedy character, though.
Even in Last Crusade, Indy shows signs of greed when not wanting to let go of the Grail, and his Father snaps him out of it. Indy knew very well that finding and bringing back the Grail would put him as top archaeologist and make him famous beyond his wildest dreams.
The Treasure Of The Sierra Madre has been highly referenced as an influence for Indiana Jones.
The character of Indiana Jones did not come out of a vacuum. Indiana Jones is a composite/compilation character of both historical figures and fictional characters.
Many of the fictional characters George Lucas and Steven Spielberg grew up watching on film have classic literary backgrounds or pulp magazine material.
