Valuation Request for Star Wars original trilogy Postcards

[rab.ixii]

Hey I've been doing a clear out and came across 3 perfect condition postcards from the original star wars trilogy.
The back reads Published by Classico San Francisco, Inc. TM & Copyright 1997 (1980 and 1983 depending on the postcard) Lucasfilm LTD.

Dont know much about pricing with this stuff and cant find them online so if someone could help me out that would be great.

I will post a picture in another comment from my tablet, sorry about the quality of the photograph,

Thanks in advance.

If you put stamps on them they'll be worth more

No, they will actually owe you the cost of the stamps.
