Question I recently purchased an Olympic poster of the Gymnast by Colleen Browning. It is a signed poster in excellent condiditon. How do I obtain a certificate of authenticity? Do you know the approximate value of this item I purchased for 10.00 at an estate sale.
Answer First, I do not think you can obtain a certificate of authenticity. Who would issue it? I can think of no agency that could. However, it is possible that we can find some information about your poster. But I will need more information.
Is there a date of those Olympic Games in the poster image? Who signed it? Can you make out the signature? Could it be Peter Max?
I want you to look at the poster with a magnifying glass. You will be looking to find if the poster were printed on a printing press or was done by serigraphy. A poster printed from a press would usually have little dots to create the shades of color (look at a colored page in a magazine with the glass, and you will see what I mean). If done by serigraphy you should be able to detect the very thin layers of ink. You would not see this in a poster from a press. If it was printed from a press, the value might not be great, but if it is signed by the artist or the gymnast, it might have some value.
You say it is excellent shape. Here are some tips on keeping it that way. Keep it out of the sunlight at all costs. Go to a local art supply store and see if you can buy some paper a little larger than the poster that has NO acid content. Put the poster between these sheets. If it is in a frame, remove it from the frame and put an acid free paper behind the print.
So, I look forward to more information, and we will see what we can find.
Under any circumstance, you got a great deal for $10.
