Limited Edition
I'm looking at this one for a limited edition but need some ideas from others who've gone there.
It's a 4:5 ratio, so 16x20, 24x30, 36x45 or 40x50 would be the potential sizes. Should I go with multiple sizes or choose one and stick with it? I've had it printed at 24x30 and that looks great.
Also debating media - print, or acrylic? (I'd thought of metal because of the subject matter, but suspect that's not a great option for limited editions.
This would be a maximum of 30 and retired after that number is reached. Suggestions for a certificate of authenticity? What else should I be aware of or be sure to include?

Where will you sell these limited editions? How long until you sell them out?
I'm glad I asked questions. 🤔This one, I never even thought of... They will be listed on my website at least, and based on the limited editions of another photographer I checked out in advance of planning this, it can likely be anywhere from a year or so to several years for them to be sold out. Which brings another question - can they be printed on demand when someone is interested?
Why are you making a limited edition for this image, I mean, why this one? How does making a limited edition help you?
Thank you for the questions that make me review my motives. This image (and one other that I also want to make a limited edition) in my collection really make me think. This one brings back memories because it was a common sight years ago in small towns (and this bookworm looked forward to the monthly visit!), but it's an image viewers stop and really study. I feel like making it a limited edition will create a little more urgency with those who are interested - it's not like, "I can order this any time."
