Translation Request from Polish #translation

Leon Goliger
Dear Fellow JewishGeners:
I am looking for any possible assistance with translation of the two images listed above that are posted on Viewmate. These images are the front and back of a postcard from the home of my great grandfather Leib Goldblatt in Jaslo, Poland to my maternal grandmother in New York. 
It apparently has some information regarding my grandmother's sister who relocated to Buenos Aires, Argentina. 
Any assistance with as thorough a translation as possible given the limited quality of these images from a postcard that was written in the 1920s would be greatly appreciated. 
Thank you, 
Leon E. Goliger, M.D.
