Nelson,
Barry answered your question better than I. However, I haven't seen anything published that said less than 75years. It all depends on so many variables though. Paper, humidity, display/storage conditions, etc. Everything published is based on accelerated aging tests using lights at certain distances and intensities 24/7. These tests, though standard in the industry, may not replicate actual conditions. Still, for comparing one print to another they give some basis for making judgements.
