"Arts and Crafts" Studio Pottery Vase signed "JLG"?

I recently acquired this slab constructed studio pottery vase which I would describe as "Arts and Crafts" in style. The bottom had been covered some time ago with felt which I removed to reveal the signature. Although somewhat open to interpretation my reading is "I L G" or "J L G" for the top line; and "12-49" for the second line. It is possible that this second line is a date - the style is appropriate for that time frame, or it could simply be a style/artist/inventory number. It measures juust about 8.5" long by 5.5" across and 5.5" tall. I have been unable to identify the artist so would welcome any suggestions as well as general comments on the piece. Thanks
