I examined every DOT on the bowls and conclude they were never used. NO chips, NO cracks, NO scratches, NO paint loss. The box is as close to perfect as could be found for an OPENED BOX. Only the top lids have a bit of cardboard separation from being pulled open from the glue.
One side of box reads. 4 pc MIXING BOWL SET (now 3).
FROM: GEORGE I FELDMAN COMPANY INC BOSTON 10 , MASS. TO: RIVERSIDE PARK , AGAWAM MASS (see more about this below).
Another side of box reads. 1 5 BOWL (the broken brown dot), 1 6 BOWL, 1 7 BOWL, 1 8 BOWL. And the fourth side reads. DIVISION OF CONTINENTAL CAN COMPANY, CLARKSBURG W.
A LITTLE HISTORY: This park opened in 1870 when most patrons arrived from Springfield by steamboat on the Connecticut River. Well, the bowl set was never used, so not used in the Park food service. So, I can only speculate that it may have been a prize in one of the games of skill or chance at the Park in the 1950s 1960s and went home to the nearby town (Palmer MA) where I got it, and stored away in the attic. I was a frequent visitor to Riverside as a kid in the 50s 60s...
