Here is a great website that included the answer to my question, but it has
other symbols that may be useful too, like wheelchair access, assistive
listening devices, large print etc.

Several people correctly suggested searching Google Images, however one
drawback is when  searching e.g. "sign language" the retrieval is
overwhelming instucting HOW to sign. BTW, there are numerous great websites
with animation and video for learning to sign.
