Victor's last name is an Easter egg. When it was founded in 1939, the company that became Marvel Comics was named Timely Comics.
The Norse diorama has statues of Odin, Thor, and Balder, whom Loki dislikes. In Norse mythology, Loki was a jealous rival of Balder and conspired his death.
The statue of Balder has him bearing a horned helmet. This was his design by artist/writer Walter Simonson in the "Thor" comics.
