Can’t believe they would ship it like that, but excellent pickup none the less. It’s a classic early LA Dodgers pennant, and their best one post-Brooklyn IMHO.

Just use a steam iron on medium-high heat from the reverse side only. Keep the iron moving, and not in one place for too long. Place the pennant face-down on a smooth clean surface prior to ironing… preferably plain white or beige, to ensure no color migration. The creases should come out just fine, but remember to apply just a little iron contact at a time, just to be safe.

Best of luck, and please show us the “before and after”.
