Summary

Media data and Non-free use rationale
Description	A petri dish showing a pattern of holes imparted on a petri dish in stage 6. The pattern is the object of discussion.
Author or copyright owner	Ariel A. Andersen
Source (WP:NFCC#4)	https://www.ncbi.nlm.nih.gov/pmc/articles/PMC290224/
Use in article (WP:NFCC#7)	Andersen sampler
Purpose of use in article (WP:NFCC#8)	To support encyclopedic discussion of this work in this article. The illustration is specifically needed to support the following point(s): "Positive hole method"
Not replaceable with free media because (WP:NFCC#1)	Any derivative work based upon the artwork would be a copyright violation, so creation of a free image is not possible.
Minimal use (WP:NFCC#3)	This photo is much larger than depicted here. Only stage six is shown to demonstrate the pattern.
Respect for commercial opportunities (WP:NFCC#2)	The use of a low resolution image of the artwork will not impact the commercial viability of the art.
Other information	As a pre-1989 work, if copyright notices haven't been explicitly added, and nothing is filed with the copyright office after the fact by the journal or the author, more conditions could be allowed, but I haven't checked.
