Maybe I'm missing something, but the table appears to lack a unique index on the natural key, which would allow duplicates. This would normally be a requirement for any table, but since this table contains a collection of things (comics), I guess it's possible to have duplicates in reality.
Also, at least on a transactional (or fact) table, I want the rows clustered in the order they are inserted. This can be the actual date of insertion, which is something you need anyhow, and it doesn't necessarily need to be unique. Maybe the date that a comic is added to a personal collection is not an important, but in most of line of business applications it is. For example a car dealership would want to know the date that a car was added to inventory.
CREATE TABLE dbo.Comic
AcquisitionDate DATE NOT NULL DEFAULT (GETDATE()),
PublisherID SMALLINT NOT NULL,
TitleID INT NOT NULL,
IssueNo SMALLINT NOT NULL,
CONSTRAINT pk_Comic PRIMARY KEY NONCLUSTERED ( PublisherID, TitleID, IssueNo )
CREATE CLUSTERED INDEX CIDX_Comic_AcquisitionDate ON dbo.Comic (AcquisitionDate);
