Hi Group. I have 1917, 1918, 1919, and 1921 Central High Helios yearbooks and will scan photos of seniors or faculty for you if you would like. Please reply to [email protected] with their name and the year that you think that they attended or were faculty. I will scan the photo(s) and send them to you in JPEG format. If anyone out there has a 1916 Helios and would like to trade or sell it, PLEASE let me know. Regards and stay warm. Doug DeBarry in Saint Paul, MN
