I could certainly be wrong, sir, but my guess is that the whole point of this thread was to show these off. After all, this is what he does.
If that is the case, I did not know and am humbled. @justafarmer, I am truly sorry if that is your artwork. I started off trying to be humorous regarding the posting of drawings instead of photos and then, apparently, made things worse by assuming the drawings were not your work.
I am duly impressed, especially since they are done in CAD . . . not an easy thing to do when straight lines and constant radii are not involved.
Were this someone else's work, that doesn't get him off the hook. Leading us to believe it does is, well, misleading. Copyright is statutory. Barring any statutory exception, only a written waiver or assignment does that. Crediting the copyright owner doesn't do diddly-squat. Did I spell that right? Lol. Very, very well-done. I'm impressed.
Maybe later - Look at the two 1818 Large Cent drawings paying attention to the diameters and where they intersect the design on the opposite side. Thanks for the compliments on my artwork Here is the 1828 Quarter I just completed.
