I do not know maker or pattern - it is a lovely pedestal cake salver/stand.
Stands 6 1/8" tall to top of raised rim. Measures 9 3/8" across to outer edges, 8 7/8" inside. Base is apprx. 5 1/2" across.
Small center well - measures 1 1/8" across.
Floral design - beaded petals or teardrops - glass is flat on top, raised design underneath. Rim and base are notched. Base has panels.
Clear glass with no cloudiness.
I see some air bubbles in glass and typical lines in glass on base. The inner and outer rim edges have a little minor roughness. I do not find any chips or cracks. Surface is in great vintage condition.
Please note: From large local collection of glassware, purchased at estate sale. I am not an expert on antique and vintage glass. I am able to identify some patterns based on tiny stickers the previous owner had affixed to bottoms of pieces. I removed these when washing the glassware. I have tried to point out everything I see and have provided many photos. If I have left out important information, please send me an e-mail. The photos provide additional description and you should find close-up views of any imperfection I have described in last photo(s).
For U.S. addresses, I will ship UPS. You should see options for USPS and UPS at checkout. You may pay least expensive option to your zip code, but I will still ship UPS. For Canadian addresses, I will ship USPS Priority International.
