Susan and I were able to figure out a few of them.
I love this one, it's either Baba or his brother Charlie:
That goat is kind of scary though.
This photo is labeled (one of the few) "1912, store Pike Place Market Seattle" with "Ma" and "Pa" identified as the two people standing at the left and right. We know that the Giustis did have a little grocery store in the market at the turn of the century, so I'm assuming these are our great-grandparents:
I love the buggy in the right foreground, and it's fun to know that our ancestors were among the original Market merchants
Okay, these two are awesome! I'm giving them to Jon, our Great White Hunter. The back of one says "1910: Dad with Deer shot at Duvall"
I'm guessing the gent on the left hand side of the pole is Baba's dad, as he looks like the guy in the Pike Street Market picture. I'm in love with Mr. Handlebar Mustache though... and their hats are too cool.
And you can bet that in 1910 it was a great adventure to trek to Duvall to go hunting. No roads (no cars probably!), that would have been out in the woods for sure.
