The picnic poster was created for the annual Fourth of July Picnic held by Willie Nelson in Austin, Texas. The event was a celebration of music and brought together artists and fans from all over the country. The 1984 picnic was particularly memorable as it was the first year that the event was held at the Austin Aqua Festival.
Garrett's poster for the picnic is a highly sought-after collectible and has become an iconic representation of the event. The poster is also a symbol of Willie Nelson's legacy and his status as an American music icon.
