Union Trunk and Luggage Co.

Hi, my Grandma gave me this trunk last summer, she can't remember where she got it from or how long she has had it for, but I can remember it in the spare room for as long as I can remember. I am looking for information of its age if anyone could help me. There is a style no. 35 something, (can't read the last no.). It is 18 1/2 inches high and18 inches wide. I have looked at lots of pictures and haven't seen anything similar.
