Vintage Snoopy & Woodstock Stationary Set from Hallmark Sealed RARE

A very bright a vibrant vintage stationary set from Hallmark featuring Snoopy and Woodstock. Based on the colors and style I would guess this dates back to the 1970's-80's but am uncertain. I have not seen any others like this so I believe it is quite rare at this point. Perfect for a collector! MEASUREMENTS: The entire package measures 9.5" by 7". CONDITION: Excellent vintage condition. This set is complete and sealed in its original packaging. The cardboard of the package is somewhat bent but does not appear to affect the stationary at all. Please see photos for details and ask with any questions. Thanks!
