My first sketches were were of a few of the Mexican Masks on exhibit in a 5.5" square Handbook journal that fits easily in my bag.
Unfortunately the food arrived quickly and these don't really resemble the named victims.
This is the old Gilcrease house which is still used by the museum for classes and storage. I ran out of brown ink in the fine tip pen I had been sketching with and decided to try another Pilot with a stub nib and I think I would call that a happy accident because I really liked using it. The breeze was nippy but the sunshine and being outside to sketch felt great.
