Thanks for all the help

16 X 20 is a standard frame size !! Great that hers is larger !!
The paper on the back is just a dust cover !! It may have publishers info on the back !! You could take it to a frame shop and have them remove the dust cover and see !! It may cost about $5.to $10 to remove and replace !!

Yeah it’s a great print. Hers is 16 by 20″ or bigger. Great Matt job as sealed in the back

It would be a stroke of luck if you ever found another like it !! These were quite popular back in the 1970`s !! They were usually small prints sold in sets of three with a different scene on each !! It was inexpensive artwork for middle America and sold at most department stores !!

Thanks my wife had this for a while and never could fine it.
