Hi. I'm offering this Lionel 260 bumper with NO RESERVE, but really it's the box that you might want to consider. (Or tell a friend who's into ephemera.) Consider:

The Office of Price Stabilization (OPS) was a U.S. federal agency established in January 1951, during the Korean War, to control inflation by setting price ceilings on goods and services. Part of the Economic Stabilization Agency, it enforced regulations via 14 regional and 90 district offices, freezing many prices until its abolition in April 1953. 

OPS was supposed to prevent runaway inflation caused by the Korean War by administering mandatory price controls. The agency was known for its January 26, 1951, price freeze, which was widely seen as unpopular and largely ineffective, often requiring upward adjustments. (What a surprise!)

More interesting (at least to me), based on the Consumer Price Index (CPI) data from the Bureau of Labor Statistics, $1.95 in 1951 has the same purchasing power as approximately $24.33 to $26.23 today, which means that Lionel (wisely & wildly) inflated the selling price (for OPS purposes) so they could have room to sell the thing at at a market price.

This box is unique in that it actually has an "OPS CEILING PRICE" of $1.95 factory-printed on it. It's in reasonable shape for its approximate 75 years. Its missing its lid on one side, but the flaps are still hanging on. See what you think--the pix should tell the story. 

BTW, I'm aso including the bumper. The light works. The grounding tab is a bit sketchy. Again, look at the pix.

Thanx for looking.
