Today on spaceweather.com <www.spaceweather.com> is a cool feature
called "Explore the Sunspot Cycle". You pick a date, and it shows a graph of
sunspot numbers for +/- 5.5 years. It goes back to 1755.
I found the easiest thing was to click on the year, and they use the mouse
scroll wheel to go back and forth over time.
Happy dreaming!
