Vintage Restaurant Ware Plate Holiday Inn Acapulco Mexico

This is a vintage restaurant ware plate from the Holiday Inn Acapulco. The rim of the plate is decorated with two stylized birds in colours of red, green, yellow, cobalt blue, brown and black - Fiesta Mexicana Holiday Inn Acapulco is hand written between the two birds. The underside is marked with an Eagle and Ceramica Pancho del Cera (?) Tonala 639 (?) Mexico. The plate measures 10 7/8 in diameter. It is in very good condition with no chips, cracks or wear, but there are two small light yellow spots on the topside, quite minor. Im unsure of its age, but my best guess would be 1960s-70s. Fun collectible display plate!
