Smallest is 1-1/8" and largest is 2-3/8". Lithos are row 1 first two, row 2 all five, row 3 first two. All the rest are cello with the exception of the "Greetings" milk bottle cap in the fourth row. All buttons are different with the exception of a duplicate in row 2. Vast majority are 1950's with one dated for 1974 and two or three others that would be 1970's or in the case of the last item probably 1990's. The only ones showing some age are row 3 #4 with a few gray marks on edges and row 4 #2 with faint age tone on outer edge of the fabric covering. A very nice clean group and the first two in row 3 are rare.
