No, it's a reproduction of a Hazel Atlas pattern, not a reissue by Hazel Atlas. Hazel Atlas was bought out in 1955. A fair number of the US Depression glass patterns have been reproduced by unknown companies not in the US; DG is a big market.
There are also examples of moulds moving to different companies within the US and being used, but these tend to be marked appropriately and are sold more openly, i.e., not on fleamarkets, which is where these first appeared apparently.
