Griffin or Dragon Mark on a small sterling frame?

Just wondering if anyone recognizes this mark? It looks like a dragon or a griffin to me, and it's on a the back of a small ornate sterling photo frame. Thanks so much!

::: Seems like it could be "H.H. Curtis & Company" based in North Attleboro Massachusetts circa 1890 to 1915 :::
:::::: There were a few slightly-different variants of the hallmark so correct me if I have wandered astray :::::::

Thank you so much! It does look a lot like that hallmark, but I can't seem to find a super clear photo of the Curtis Company hallmark, so I'm not certain! I'll keep looking and see what I can find. Thanks for your help!
