Vintage Marvel Films Envelope 0

[Hiro]

Another discovery as I go through boxes that haven't been opened in a few years. Found this Marvel Films envelope. Not sure of what year or what was in it.
Measures 12.5 x 9.5 - Sorry for the crappy pics, but cool MF Spidey logo! Anyone have any info on this?

Should probably start doing more research before I post, but found some info on the history of the MF logo here:

Looks like a version of the Marvel Films logo on the envelope was Marvel Productions 3rd logo used from Sept. 1986 - Dec. 1993
