Original / Vintage 1969 Seattle Pilots Felt MLB Baseball Pennant Flag & 1977 Seattle Mariners Inaugural American League Opener MLB Baseball Pennant Flag (2 Pennants Total). Standard Size Pennant Flags 30x12. Ok first of all we know that these are technically (2) different franchises (the Pilots became the Brewers) but since they were both Seattle teams we hope someone from there will enjoy them. The 1st flag belongs to the Seattle Pilots which only existed for one season (1969) before they were bought and eventually transformed into the Milwaukee Brewers. The 2nd flag is actually quite rare as it was made for the 1977 Inaugural AL Opener at the Kingdome in Seattle. Please see images for details regarding condition.
