Great score.This is a 1950's United Airlines menu as you can see.
I have one unfolded and unprinted which is more sought after because
suitable for framing -it doesn't have creases in it.Yours is still
very suitable for framing and appears to be in great shape.
The artist kinda looks like Stan Galli that created alot of the
United Airline promotional posters in the 1950's and 1960's but
it's not The artist name Fener is to the far right just above the
ukelele leaf.I really am not familiar with this artist.How I can
tell this is from the 1950's is the style of the animated characters
used in the scenes.To the best of my knowledge this is part of a
series of scenes they did to promote Hawaiian travel.I have seen
several others which I have one as well and will try and post.
A majority of these did not make it.They either got soiled, stained
or tossed.As far as a value at least $ 50-$75 .Unfolded $100-$125
Where did you find yours ?
