YN Giveway

Attention all YN's -
I have a very slightly damaged copy of a color poster of the photo used on the front of the Lester Merkin's Helfenstein sale of Large Cents. It has wrinkles on one edge due to the USPS running over an end of the shipping tube. This was purchased from Charlie Davis, and he did not want the damaged poster back, so free to a good home it will go. This is from the limited set of 100 done in 1996 and it is 20 x 24" (e.g. not small). Sans the wrinkles from the tire tracks, they sell for $150.
This is a pic of the catalog cover, the poster is this, but less cropped:

Free to the first YN who can provide the answer to this question:
What was so special about Lester Merkin's Helfenstein sale?
Please include your age with the answer. Good luck!

The correct answer is that it was the first auction catalog with a color image on the cover.
That didn't take long. Good job YNs!

<< <i>We have a winner. I'll post it later. Multiple folks got it right. Some entrants were old enough to have YNs of their own. But they did disqualify themselves.

Oh well. My son was a little slow with the answer but I am glad he got it correct.
