Hello All, I have a glass maker's mark on a vase (a cow or steers head) which I cannot identify; any help in identifying the mark would be greatly appreciated (see attached photos). Thank you! iliad3.

No answer, but I also want to know the maker of this glass.
I have 2 perfume/dresser sets with the same mark on the bottom.
I have searched books, web sites and antique marts with no luck as to the manufacturer. Given the fact the perfumes have plastic atomizer caps, my assumption is that the glass is from the late 40's or 50's. My pieces are satin glass, one in pink, the other white.
Any response?
