The Lionel Billboard Set No. 310was first released 1950 and production continued until 1968. It was issued with ten folded card stock billboards and five frames to hold them. The billboards would change each year and they are a testament to the advertising of the period.
Until 1956 these billboards have the word "STANDARD" printed on them, after this date this imprint is not shown. Over 50 different billboards were made for this set and value is contingent on which billboards are included and if they are not separated.
The billboard frames would work with theNo.410billboard blinker. Also see theNo.B310issued in 1966 and 1968 in blister packs.
There are two variations:
Variation A:DARK GREENbillboard frame.
Variation B:LIGHTER GREENbillboard frame.
Dimensions:Base: 5-7/8" x 7/8", Height: 3-1/4"
