There are two different v3#1 issues, one with a date of January 1968 and the other dated February 1969. Though Eerie usually starts new volumes with each calendar year -- so calling the January 1968 issue v3#1 made sense -- they numbered the rest of the 1968 issues as volume 2, so we list the January 1968 issue as v3#1 [v2#5] to distinguish it from the February 1969 issue numbered v3#1.
