Has anyone ever soaked a Baseball Magazine Premium

[Runscott]

Job done on the National Copper Plate supplement. The semi-glossy surface made this very easy - very similar to just soaking a T206, but even easier.

The glue was not the simple stuff where the unwanted paper slips right off, but it wasn't the impossible stuff either - it required gently tugging and scraping. Glue had been applied only along the left margin of the Sporting Life newspaper photo, about 1/2"- 3/4", very heavily. I started by dipping that part of the supplement in a tray of water, but eventually just fully submerged the entire thing and let it soak. There was a tough area where the glue didn't want to let go - I lost two small spots of the black border lines.

The EASY part was drying it. The soaking even took several creases out. I kept blotting with typing paper until it was completely dry and flat - there was no warping at all. I then put it in a large piece of blotting paper and weighted it down under some books for about 2 hours. Job done. Just the two small bits of paper loss, a touch of glue residue, and some minor staining where the newspaper picture had been.

Thanks for the suggestions!
