This is a 1968 HemisFair postcard. The HemisFair was held in San Antonio, Texas from April 6 to October 6 1968. The card depicts the artist's model of Las Plazas del Mundo (Plazas of the World) in the HemisFair's International area, where more than 30 foreign governments had exhibits.
This Plastichrome card is unused and in excellent condition It will be an interesting one to add to your World's Fair collection.
All my cards are shipped in a plastic sleeve in a rigid postcard mailer.
