How to remove lumber ink stamp??!

We are working on our first big project building a new dining room table (inspired by C&B's Big Sur table). Some of our newbie mistakes are that we just assumed the lumber stamp would easily sand off and now we are prepping to finish our beautiful table and Can't Get The Ink Off! Help! It seems like there must be an easy fix for this! Right? Right?! 
Also, we were a little careless with the wood glue and also assumed it would just sand off but nope. How can we get this off?
Our table came together so well but now that it's time to sand and stain we're feeling defeated by these mistakes. Hopefully they are fixable? Thank you for any help you can offer!
