The 14 Standard Cover Collection

The first 13 are reprints of the originals seen here. The publish dates for these are from the copy I have. I am not sure when the new cover came into effect. The dates from #14 to #39  are when the first printing was done on them. The cover illustrations were done by Hector Garrido.
