Sounds like a "banana boat"....but we need pictures to really ID it.

Is it a treble clef or could it possibly be something that looks like a cursive L?

Not an I G with 1 imposed over the other, that is Imperial Glass. Viking had a lot of vases, rose bowls but they had clear sticker on them. Is it completely plain or is there a design etched? A.H. Heisey made unusual items but their molds were sold to Imperial in 1958. Both companies are gone now. pic would sure help.

how do I post photos on here?

Go to Photobucket or another picture sharing site and follow their directions.

Embarrassing though it is.....I never saw that mark and can't find anything about it on line....sigh.... LOL!
The dish looks like depression glass in the form....I can't get a good picture of the color...but it looks like that depression glass pink.
I have a huge list of who DIDN'T make it...Jeanette, anchor hocking, Fenton, Fostoria, Imperial, Heisey....
Well you get the idea!
I believe it dates to about 1930 to 1950...not sure if it's american....a picture showing the color will be a better indication....and I think it's a very nice piece. It's commonly called a Banana Bowl...yes made form the mold of a plate that has had the sides pushed up while it's still not set. It was used as a center piece for a table usually with fruit....and I'll bet there were candle sticks to go with it.
Sorry I can't put a name on it.
