Irving Amen's works are most commonly prints, as he is considered a master print maker in woodblock, etching, lithography and silk screen; this example appears to be etching or etching with aquatint. He also executed oils and acrylics in the course of a long career. This work, titled at lower left in pencil "Tenderness" and numbered there 89/200 examples, is signed in pencil at lower right. The print measures 18 3/8" by 12 1/4" inside the mat (23 1/2" by 17 1/2" as framed). Note the pale pink and blue colors. Judaica subject matter is common for Amen, who also focused on children as subjects. The artist was born in New York and was precocious, exhibiting in his teens. After World War II he worked in the US and Belgium on murals (you can see from this work why he'd be successful as a muralist). He exhibited at the New School for Social Research. Later in life he has taught print making and sculpting, and as of the 1990's he is recorded as a resident of Boca Raton, Florida. See the net for much more on the artist.
