Great idea.

EmilySue, I've curated a few Duluth-Superior shipping-related galleries on flickr, and have them set up by decade up through the '80s.  None of the images are mine, but the galleries are a nice way to gather similar stuff.  Feel free to peruse them; if there are things you want included in your group I'm sure many of the users who've uploaded the images would gladly join the group and contribute. 

Try this link: Waterhause's Photostream.

You'll see that the "Str. Noronic" postcard and a few other images are already included in the galleries and that'll lead you to the rest.  Thanks for putting this together, it's a fantastic idea.

I used to beg my dad to drive over that bridge!  I loved it even though it terrified me.
