Hello, I am hoping someone out there can help me. I acquired this bottle years ago, in the 80s, in Bluffton, Indiana where it originated at the Steury Bottling Company started in the 1930s. However, although this company is known for the commonly found ACL Heart's Club soda bottles, I have not been able, as yet, to uncover more information on this beautifully detailed embossed Heart's Club bottle, nor have I ever seen another one. I have tried everything over the years from researching the company, contacting wells county chamber of commerce and even a failed email attempt to a Steury family member. Please look at attached photos and I would greatly appreciate any information from anybody who knows anything or has seen one before, thank you. the only marking on the bottom is 21-7
