Cool idea of an all marked set...and 66, that will be a fun challenge, one of my favorite sets. I have spent a lot of time continually upgrading my 66 set and when I put it together I had lots of doubles...your post sparked a memory that I did have a uniquely marked 66...went to my doubles binder and there it is. Quite frankly I think the "artist" made ol Jim Perry look better...
Maybe more Frank Zappa with a buzz cut...but pretty funny.
If you need this for your marked set PM me your address and I will ship it over to you.
