Having items graded by PSA at Chicago show-what to expect?
 

I’m jumping in and having several items graded at the upcoming Chicago/Rosemont show. Hoping to avoid long lines and any surprises. Planning on taking 15-20 items, primarily autographed items and some vintage high grade cards. Also plan on showing up early Saturday morning. What should I expect? How long will the line be? Any insight from those that have done this would be helpful. Also does PSA grade 1935 Wheaties Fancy Frames?
