X-raying of fruit

Images: from brochure distributed at 1939 Golden Gate International Exposition.

“…in the past it has been impossible to detect certain kinds of imperfection by external appearance alone. Frost damage and granulations in oranges…leave no indications on the surface…”

“This X-ray inspection unit permits the operator to look right through the fruit instead of at its surface only.”

Excerpts from the brochure.

National Orange Show

The National Orange Show was something like a county fair except that it was solely for citrus fruit. The guest pass, probably typical for the times, has a blank for the guest’s name followed by “and lady.”
