So there’s a Pop Kill: Seasonal Flavors series recorded on the Core, but the only entry is a duplicate of the book recorded as #1BW of the main Pop Kill (Mad Cave) series (Alison Sampson cover).
Seems it’s just a reprint of #1 of the main series; assuming it’s titled Seasonal (or possibly Holiday) Flavors in the indicia, I guess #1BW (and possibly also #1BX, the Elsa Charretier Valentine’s Day edition due in February 2026) will have to be removed as duplicates of issues recorded under the new series.
Bird City Comics have already released eight exclusive variants of what they are calling Pop Kill Holiday Flavors #1:
Cassandra Dunn Nice cover (limited to 150) (Metal version limited to 25)
Cassandra Dunn Naughty cover (limited to 100) (Metal version limited to 25)
Andrew Tarusov Nice cover (limited to 100)
Andrew Tarusov Naughty cover (limited to 100)
Andrew Tarusov Nice Metal cover (limited to 20)
Andrew Tarusov Naughty Metal cover (limited to 20)
I think these should be added to the Seasonal Flavors series; I assume all variants will be under the same name (whether that be Holiday or Seasonal Flavors).
