The Yiddish is as follows:
Dear devoted friends, Efraim and Perele Wechsler may you both live,
We wish you from the depths of our hearts, a good blessed year, full of all the good as you desire for yourselves, all in it's right auspicious time- Amen!
Your close friend, from way back
Rabbi Menachem mendel Rabinowitz and his honored (?) Wife Miriam, may she live.
