In spoon collecting we have two types of
Navajo spoons.
First we have the spoons that were made by Navajo indians
for the tourist trade. Second we have spoons made in a
generic indian style by silver manufacturers which were also
catering to the tourist trade.
The symbols found on Navajo spoons are not necessarily related
to the Navajo way of life, but instead were symbols that the tourists
expected to see on Navajo spoons, thus creating a salable product.
The Navajo's did not make silver spoons for their own use.
Navajo indians typically learned their silver making skills from
Mexican silversmiths and then they passed the skills onto later
generations. Eventually indian schools established by the Federal
Government to teach the Navajo's occupational skills also taught
silvermaking skills.
