Original 1st printing 5&1/2 x 8&1/2" concert handbill for Led Zeppelin appearing at the Met Center in Bloomington, MN on 4/12/1970.

 Designer unknown/not credited, thin flat stock handbill is in near mint to excellent (A-/B+ to B+) condition; aside from a VERY light amount of handling wear and a slightly rough lower right margin/edge (as issued, I have had three identical examples from different sources), it is a SUPERB-looking low-run regional Zeppelin concert artifact from a fairly early US tour. 

 Check out an audience recording of the classic "Bring It On Home" from the show HERE:
