I contacted, purchased ($150 USD) and received a rough .pdf from the MERCEDES BENZ CLASSIC CENTER (classicdatacards@mbusa.com) in December 2020 of my 280SL's data.
I then forwarded that single image file to alpinaltd and within a day he returned fantastic artwork to me replicating the 5 original cards (3 in manila/tan(front and rear) and 2 in pink). Alpinaltd's artwork included the proper fiducial markers for print registration and for cutting from card stock and trimming for both square and radiused corners as indicated.
With his artwork, I had the cards jet printed at Southport Printing on Islington Street in Portsmouth, NH on 271gsm weight stock.
I couldn't be happier with the end product. The level of detail in alpinaltd's work is top notch.
