Now I see where I need to post this message. I'm learning the forum and have 2 lamps that I could use help with to ID, one is marked Fertig who I have not heard of and dated 1951. The other looks like the roseville aztec in shape and form but I can't find it anywhere. Here is a link to pictures on photobucket. One flower has an a in blue ink and the number 1 on another and what looks like the rv in yet another flower? any ideas? thanks.

I am thinking these are not Roseville. Shots of the bottoms help in the identification of pottery regardless if there are no markings. Mac
