I don't know if anyone posted about this already or not, I just found out about it the other day.
According to Amazon, DC Comics is going to release a hard cover collection (similar to the Showcase Presents) of the first 26 issues of Super Friends. They are listing the date as 12/31/19.
I don't know if it will be in color or black and white (like the Showcase Presents was).
