About 28.5" excluding tassels (if any tassels are shown).  Date is best estimate, if shown in title.

Neat old UC pennant!
 
White veritical strip on left side is a little dirty/dusty...a few light stains around the Buffalo artwork.  The rest is in overall good condition. 

I ship pennants in a bubble envelope.  Smaller ones are shipped flat.  Longer ones with one or two folds - lightly folded with tissue paper placed at the point of the fold.  I have shipped thousands of felt pennants this way with minimal issues.  If you want it shipped another way, I will gladly work with you, but please ask what it will cost before buying.  My shipping cost as quoted is via a bubble envelope.  Thanks!
