The label says that this object was created for the tourist market. Does that mean it (or something similar) was not used by the Iroquois people pre-Columbus?
Great question! You're right, objects like these aren't exactly tradition to the Iroquois before European contact. Beadwork certainly was traditional, and the Iroquois developed and honed that craft for the market, developing specific patterns and motifs that could appeal to European Americans.
For instance velvet, silk and glass beads weren't materials these people would have used prior to European contact. Likely they chose silk and velvet because European Americans enjoyed and treasured those materials more so than traditional suede or animal materials, thus making a product easier to sell.
