Bessie Coleman nee Irwin; Elizabeth Maxwell Irwin, elder daughter of R. P. IRWIN.
Photographer: E & J Lauder, 22 Westmoreland St., ( facing Ballast Office ), Dublin
NOTE: There is something written ( and underlined ) above the inscription, possibly Mo, but due to R.P. Irwin being labeled as Grandaddy. I wonder if this is the mother of the original owner of the photos - she certainly isn't named as Aunt so perhaps the word is Ma.
