IMHO, my guess would be more contemporary studio..... the pontils seem to be indicative of more modern work as they appear to be flamed, and not cold worked... most (not all) contemporary artists seem to dislike the cold work required for a nicely polished pontil.... No idea on house or artist....
I am also assuming, since your location is not shown... which can be helpful sometimes.... and can be changed in your profile.... that with a Comcast email address you are in the US somewhere..... and that would also fall in line with contemporary studio of this kind....
The shape of the bases seems a little linear to me to be older work.....
