Wall of Blue Agave Plants and a Harvester, Painted Glass

A long glass wall behind the bar of a Mexican restaurant, painted in transparent blue, green and yellow with a field of agave plants and a figure in a hat with a long-handled tool in the corner, probably an agave harvester. Close-up photographs show the colour flaking away in places, which suggests cold-applied paint rather than fired glass paint. Glass seen; method not confirmed.
