Physical Graffiti (1975)
Display, Inflatable Blimp (Japan)

From Japan, this is an extremely limited promotional blimp used for the Physical Graffiti release. While some have said this an orange color, it is definitely red.

The yellow blimp and the red blimp are identical in design, even down to the spotty Swan Song printing on the tail.

A similar style blimp was release for Coda, except the Led Zeppelin letters are in Coda style, and the blimp material is shiny.
