The image shows three rectangular plaques on a concrete pavement. The plaques are made of metal and have text engraved on them. The text reads "Leo Silbermann", "Rosa Silberman", and "Margot Felicia Silberman". 

The plaques appear to be commemorative plaques, as they are rectangular in shape and have a polished finish. Each plaque has a date and time engraved on it, indicating that they are located in a public space.

On the left side of each plaque, there is a text that reads "Hier wohnte" which translates to "Happy Birthday" in English. On the right side, there are two smaller plaques that read "Departure 1943" and "Auschwitz Ermordet".

At the bottom right corner of the image, there appears to be a small plaque that is not clearly visible.
