Dear Ms. Wallin,
Thank you for posting your request on History Hub!
According to the obituary for Pearl Jasen published in the Greeley Tribune December 9, 2004, she and her then husband J. D. Harsh founded a private aerial photography company called Photo-Maps in Belleville, Kansas during the early 1950s. You may wish to contact local historical societies regarding the disposition of the company’s records and photograph collections. For example, the Republic County Historical Society Museum located at 615 28th Street, W. US Hwy 36, Belleville, KS 66935, which has the phone number 785-527-5971 and the email address email@example.com. You also may wish to contact the Belleville Public Library, 1327 19th Street, Belleville, Kansas 66935, via telephone at 785-527-5305 or by email at firstname.lastname@example.org.
We hope this is helpful. Best of luck with your research
