ID Help Please! Murano (?) maker's mark "Jack-in-the-Pulpit" style Vase

After I bought this vase I was looking at it carefully and thought it had a "flea bite" on it. I got out my loupe and saw that it looks like a mark. It's very hard to tell what the mark is. Does anyone recognize it, or have any idea what it even is? My niece thinks it's a ship. It was very hard to get a decent photograph-let me know if you think I need to try again.

Not a makers mark, likely just random. It does look crizzled so perhaps a result of a drop of the glassmakers sweat falling on it... Fanciful admittedly!

The item itself is the kind of thing often found in TK Maxx with 'Arte Murano' labels, likely made in China.
