Hi-
I got both of the pennants pictured below at the Brimfield antique show in July. I traded with a friend to get the basketball pennant and I bought the football one at the end of the week. The basketball one is oversized and has a tag on the back showing Pacific Pennant & Advertising CO 244-245 New High Street Los Angeles California. The football one is for a game that benefits the Shriner's hospitals and is between High School all star teams from Vermont and New Hampshire. The game is still played today.
