To be remembered to me in my student's years I went by the bus. And all tickets which was given to me by the conductor, I collected during 2 years in my purse. Unfortunately, on the expiration of time they were lost. And it was very interesting material for use somewhere in design. Recently I have found a site in the Internet about history of the Argentina bus tickets. Below their small part is presented. To whom it will be interesting all to history, here its source, but in Spanish.
